How do you determine the size of a house when buying a house?

1. It is normal for the area agreed in the pre-sale contract to be different from the actual delivery area, and at the time of pre-sale, the developer only has a tentative area, and when the property certificate is issued, the real estate surveying and mapping department will issue a surveying and mapping report to determine the actual area of the property.

2. The following opinions are for reference on the handling of similar problems:

1. First of all, look at the agreement on the area difference in the "Pre-sale Contract", and if there is an agreement, it will be agreed.

2. If there is no agreement in the contract, it shall be in accordance with the law: according to Article 14 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Cases Involving Disputes over Commercial Housing Sales Contracts.

If the floor area or floor area of the house unit delivered by the seller is inconsistent with the area agreed in the contract for the sale and purchase of commercial housing, and there is an agreement in the contract, it shall be handled in accordance with the agreement; If there is no agreement in the contract or the agreement is not clear, it shall be handled in accordance with the following principles:

1) If the absolute value of the area error ratio is within 3% (including 3%), and the settlement is based on the facts in accordance with the provisions of the contract, and the buyer's request to terminate the contract shall not be supported;

2) If the area error exceeds 3% of the absolute value, and the buyer's request to terminate the contract and return the purchase price and interest paid, it shall be supported. If the buyer agrees to continue to perform the contract, and the actual area of the house is greater than the area agreed in the contract, the buyer shall make up the price of the house price within 3% (including 3%) of the area error ratio in accordance with the agreement, and the seller shall bear the part of the house price with the area error ratio exceeding 3%, and the ownership shall belong to the buyer; If the actual area of the house is less than the area agreed in the contract, the seller shall return to the buyer the price and interest for the part of the area error ratio within 3% (including 3%), and the seller shall return the house price to the buyer twice as much as the part of the area error ratio exceeding 3%.

3. In addition, pay attention to whether the increased area is the area within the suite or the shared area, for example, there are special regulations in Shanghai: if the shared area increases, the buyer does not need to compensate for the difference in housing price.

How should the area of the house be calculated?

The sale of commercial housing is based on the floor area. First, the overall sales of commercial housing, the sales area of commercial housing is the construction area of the entire commercial housing (the basement as a civil air defense project, should be deducted from the construction area of the entire commercial housing). 2. Commodity housing is divided into sets or units**, and the sales area of commercial housing is the sum of the construction area in the suite or unit (hereinafter referred to as the building area in the suite) purchased by the buyer and the public construction area that should be apportioned.

The formula for calculating the sales area of commercial housing: the sales area of commercial housing, the construction area in the suite, and the apportionment of the public construction area. Article 7 of the rules for the calculation of the sales area of commercial housing and the apportionment of the common construction area of the set of acres is as follows

1. The usable area of the house in the set (unit) shall be calculated according to the method specified in the "Code for the Design of Residential Buildings". Other buildings. In accordance with the method specified in the special building design code or with reference to the "Residential Building Design Code" to calculate the calculation.

2. The maintenance or load-bearing walls around the use space of each set (unit) of the commercial house have two types: common walls and non-shared walls. The partition wall between each set (unit) of the commercial house, the partition wall between the set (unit) and the common building space, and the external wall (including the gable) are all common walls, and half of the horizontal projection area of the common wall is included in the area of the internal wall of the suite. The area affected by the horizontal projection of the non-common wall is all included in the area of the wall in the suite.

3. The construction area of the balcony shall be calculated according to the current national "Building Area Calculation Rules". 4. The calculation of the construction area in the suite is as follows: the construction area in the suite = the usable area in the suite + the wall area in the suite + the balcony construction area.

Before calculating the area of the house, buyers need to understand clearly the areas related to the house, that is, the construction area, the area of property registration, the area in the suite, and the shared area. Generally speaking, property right registration mainly includes the area within the suite and the shared area, and the construction area also includes the area within the suite and the shared area, but the property right area and the construction area are not necessarily equal. Because the property right area refers to the floor area of the house where the property owner has the right to the house in accordance with the law, it is recorded in the property right certificate and is determined by the real estate department of the municipality, city and county.

Regarding the building area, in fact, it mainly refers to the measured area of the house, that is, the peripheral horizontal projection area of each layer above the foot of the external wall (column) of the house, which is directly related to the practical area and utility rate calculation of the house. Although they are now high-rise residential buildings, most of the houses are single-storey buildings, and the floor area is calculated based on the area of only one floor, including the outer horizontal area above the corner of the building's exterior wall. In the case of a multi-storey house, the floor area is calculated as the sum of the floor area of a single storey, and the ground floor is calculated as the horizontal area of the periphery above the corner of the outer wall of the building.

The above is a summary of the second phase of Changsha Helenbergh Love Me City about the calculation of the area of the house when buying a house, I hope it will help you.

1.the total number of square meters derived from the length of the living room multiplied by the width; 2.the total number of square meters derived from the length of the bedroom multiplied by the width; 3.

the total number of square meters obtained by the length of the kitchen; 4.the total number of square meters obtained by the length of the toilet by its width; 5.The square of the house is multiplied by the length of the house by the width, and the result is the square number of the house.

It is to estimate an area according to the design developer, and this contract area is inaccurate. After the surveying and mapping registration, there is the real area of the real estate certificate, and then the excess refund and the deficiency are calculated according to the registered area.

1. Usable area.

The usable area of a dwelling refers to the sum of the net area directly used by the residents in the floor plan of each floor of the dwelling. Calculating the usable area of a dwelling can more intuitively reflect the use of the dwelling, but it is generally not used to calculate the usable area in the purchase and sale of a dwelling**. There are some special provisions when calculating the usable area:

Indoor stairs in duplex dwellings are included in the usable area according to the sum of the area of the natural floors; Chimneys, ventilation ducts, and pipe wells that are not included in the structural area are included in the usable area; The thickness of the interior wall decoration is included in the usable area.

2. Saleable area.

It is the balance of the "floor area" after deducting the common shared area.

3. The area in the suite.

Commonly known as "floor tile area". It is a concept of content space after deducting the space occupied by buildings such as columns and walls on the basis of the usable area.

4. Common area.

The common area of the residence refers to the sum of the public corridors, stairs, elevator rooms, and water tank rooms set up in the residential building for residents to facilitate access, normal communication, and ensure life. There is a problem of apportionment of public area in the construction area calculated by the developer when the commercial housing is **.

How to deal with disputes over the area of commercial housing.

1. The treatment method of the increase or decrease of the construction area apportioned by the common parts. If there is an error between the area agreed in the pre-sale contract and the area measured at the time of delivery, the area error ratio shall be within the limit (including, the total amount of transfer agreed in the pre-sale contract shall remain unchanged. The formula for calculating the error ratio of late finger imitation area is as follows:

Area error ratio = [(measured common parts share the construction area to make the hunger - **common parts share the construction area) **common parts share the construction area] 100% of the area agreed in the pre-sale contract and the measured area error at the time of delivery refers to the error caused by other reasons except for the change of the building design. If the measured area is greater than the area agreed in the pre-sale contract, and the area error ratio is exceeded, the buyer shall not bear the excess part of the house price; If the measured area is less than the area agreed in the pre-sale contract, and the area error ratio is exceeded, the real estate development and operation enterprise shall refund the excess part of the house price.

2. The treatment method for the increase or decrease of the construction area in the suite. The construction area of the suite shall be handled according to the principle of "settlement according to the actual situation", and the real estate development enterprise shall negotiate with the buyer on an equal footing according to this principle, and agree on the specific treatment method through the pre-sale contract. If the contract does not stipulate the treatment method, and the measured area is greater than the area agreed in the pre-sale contract, the buyer shall not bear the excess part of the house price; If the measured area is less than the area agreed in the pre-sale contract, the real estate development enterprise shall refund the overcharged housing price.

Lord

The sales area of general commercial housing is the sum of the sales area in the suite and the apportioned common area, and the most useful area for buyers is the usable area in the suite, because this kind of area is really able to be used by buyers. Generally speaking, the proportion of the usable area to the construction area is about 60 70, for example, if you buy a 100 square meter house, after removing the common area and wall area, there will be more than 60 70 square meters of usable area.

1. Calculate the area based on your own economic ability.

Buyers with good financial ability can buy a large area of the house, such as a 120-square-meter house or a more closed house, so that the buyer can do it in one step, and can also save the trouble of changing houses in the future. However, for buyers with poor economic conditions, don't just consider one step, buying a house is not just a matter of paying for the house, but also decorating and maintaining the house.

2. Calculate the area according to the total household income.

Generally speaking, we can multiply the total annual income of the family by 5 to get the total affordable house price, and then use the house price to work backwards to calculate the size of the house. For example, if the house price income in Xiao Li's city is 10,000 yuan, and the total annual income of the family is 300,000 yuan, then the optional area is:

30*5 1=150 square meters.

3. Select the area according to the tax expenditure.

Buying a house requires paying taxes, whether it is buying a new house or a second-hand house, and the tax on the house is related to the size of the house. If the buyer buys a house that is too big, then the taxes and fees paid are also more, which undoubtedly adds a lot of expenses to the cost of buying a house. Therefore, buyers should choose to buy a house that can enjoy deed tax benefits, for example, in the 91 square meter and 89 square meter houses, you can choose 89 square meters.

Calculation of the area of the house 1, the construction area.

The construction area of the house is mainly composed of two parts, the area within the suite and the shared area, and now most developers are according to the construction area of the house, so it is still necessary for buyers to understand how the construction area is calculated. The construction area generally refers to the construction area of the whole house, which refers to the sum of the horizontal projection area of the periphery of each floor above the outer wall (column) of the house.

2. The area in the suite.

The area in the suite is usually much smaller than the construction area, because the part of the shared area has to be shared, and the construction area in the suite is the sum of the construction area and the balcony construction area within the central axis of the building in the door. In fact, the area in the suite is the part of the car area that we can really use after buying the house.

The calculation of the purchased area is as follows: house area = area in the suite + shared area; The area inside the suite = half of the exterior wall + the usable area; Pooled area = pooled coefficient * area in the suite; Pooling coefficient = the common usable area of the whole building The suite area of the whole building; The common area is the part that is shared by the entire building.

[Legal basis].Article 6 of the Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of the Common Building Area.

The floor area of the suite is composed of the following three parts:

1. The usable area in the set (unit);

2. The area of the wall in the set;

3. Balcony construction area.

Article 8. The common floor area consists of the following two parts:

1. The construction area of elevator shafts, stairwells, garbage chutes, substation rooms, equipment rooms, public foyers and aisles, basements, guard rooms on duty, and other public buildings and management rooms that serve the whole building;

2. Half of the horizontal projection area of the partition wall between the set (unit) and the common building space and the external wall (including the gable).
