When buying a house, what should we pay attention to?

For sale and for your own living, houses are different. It is agreed that more trust is given to someone who has already lived in a house built for themselves. Pay attention not only to the house itself but also to the surrounding area. Check the technical specifications of the house to be purchased:

1.Roof cover
2.Checking the keys and humidity of the walls of the house.
3.Operation of windows and doors (they should not be tilted, open well, and close without jamming). How bright is the room, does it have panoramic windows? The ratio of the window area to the floor area should be approximately 1:8. This is the minimum for a comfortable stay.
4.Integrity of electrical wires (the condition of the wires can be assessed with outlets since they are hidden in the walls).
5.Checking for leaks and puddles in sewage, heating, and water supply.

​The quality of external walls (the improper settling of the house, the absence of monolithic iron-concrete lintels in gas-concrete walls, etc. as they can cause cracks). Even if you do not notice the differences in the roofs themselves, the newly plastered wall sections can indicate their presence. However, the moisture problem is only a temporary solution, or rather, an attempt to create prosperity. Cracks will reappear very soon. If the house has a garage on the first floor, it certainly creates comfort, especially in winter. However, there must be good ventilation here so that exhaust gases do not enter the living area. There are enough nuances. Therefore, it is important to approach this issue with the utmost seriousness because you don't buy a house for one or two years. Have you already faced the choice of a house? What requirements did you have?
