See if there is an agreement in your contract. The cost of water and electricity would not have been too large. If there is no agreement that the owner claims to return it, it is ok to return it to the owner.

First look at whether there is an area difference and find the area difference. Because the house price is high, one square meter is tens of thousands, so a few square meters is also a big expense. The following is the actual area of the real estate license. First, the area of real estate license is compared with the contract area when buying a house. The contract area is 140.94. When I took the key, the developer said that the area measured by the Housing Authority was 139.39, so I returned the difference of 6 107 to me when I took the key. Check carefully that the final area on the property ownership certificate is 139.2, which is 0.65438+ less than when I took the key.

Second, look at the property maintenance fund. Property maintenance funds are collected in some places according to the proportion of purchase invoices, and some are collected according to the area. I charge 90 yuan per square meter here. Therefore, the area difference is 0.19m2, and the property maintenance fund is overcharged 17 yuan. Whether it is charged according to the purchase invoice or the area, the simplest way is to compare the invoice of the property maintenance fund with the receipt of the property maintenance fund issued by the developer, and the difference between them is the overcharged fee. The invoice amount of the maintenance fund in the following figure is 12528 yuan, which is less than that in the first figure 17 yuan. This should be returned.

Third, look at the deed tax, which is the most important. This fee is very important, because the new deed tax policy was implemented on 20 16, and the previous deed tax policy was more than the current one. At that time, the house charge was 3%, but now it is 1.5%, which is proved by deed tax invoice. So I overcharged 8249.28 yuan. This fee should be refunded to me. This cost comparison is also very simple. Compared with the deed tax paid before, the difference is overcharged.
