I am hoping to sell my house and move closer to work in about a year and have already started my list of "must haves" and "will not consider"
If lead paint is a major concern for you then it would be best to avoid houses that might have them. However if you see one you really like then you could ask that the house be tested for lead paint. Also you should consider that if the house has had major renovations then lead paint is likely not an issue anymore.
I will not consider a house with a septic tank. My brother has one it it seems every couple of years they have an issue with it. Also, there are only certain kinds of toilet paper you can use and you cannot have a garbage disposal in the kitchen sink. If I found the perfect house and that was the only flaw, then maybe. But a septic tank is a hassle I want to avoid.
I personally will not buy a house built in the 90's because of the defective siding used then. I had to spend a bundle to get it replaced on my house. I would consider an all brick house built in the 90's or if the siding has already been replaced. Otherwise I would not even consider it.
I won't consider a fixer upper. I am not handy and I hate having contractors in my house.
I won't consider a house on a busy road or that backs to a busy road because I do not like the road noise of traffic. I've lived on a busy road before and I hated it.
I won't consider a home more than 5 miles from my work because that is the main reason I want to move.
Anyway, I suggest you make a list of your "must haves", "wish list/nice to have" and "will not consider". This is going to be YOUR home so you need to feel comfortable with all aspects of the house.
