There are many things one has to keep in mind when buying/renting a house.
But the two given below are some of the most important:
A) Always get an East-facing house.This allows morning sunlight through your windows and cleanse your house of any air-borne bacteria.You are also exposed to sunlight that accelerates the production of vitamin D in your body (which strengthens your bones,remember?) and open up your chakra points (really important for the balance of your body).This is a good hack given people usually forget to or are too busy or do not care to get out of their house and take in some sun rays.Sunbathe while you oversleep.
B) Always look for windows that allow cross ventilation.You want unblocked windows in opposite directions inside the house (preferably all rooms should have at least one window) to bring in fresh air and take the stale air out.If you are concerned about the mosquitoes and what-not tiny aggressors outside the house,get a mesh with velcro or sliding doors attached to your windows.But do not get the glass windows removed because winter is always around the corner.And it is definitely here.
