I cant drive many house away to go to these things because im disabled and cannot even stay in hotels because of it.

Yes if you don’t have mortgage history this validates your primary house expense 

Assuming it is a residential property, it will be roughly 3.64% per year of the actual house/condo/townhouse/etc value (not land)

After some negotiations I have gotten a house down to 350k, 4/2.5 2500sq ft.

I am interested in purchasing a home that has been recently known as a squatter house. 

Did you buy and renovate?

They intend to renovate the property in that time and buy it with the option.

This might mean using cheaper materials or rushing the job, which can affect the durability and quality of the renovations.3.

I have never had the IRS redeem in all the years I have been buying court house steps.. and if they do they have to pay you statatory interest but you are out any rehab you did to it.. so have to be careful there you may just have to hold it 6 months is all..

I can't imagine one of these fitting into a standard house, unless it was a ranch with a near direct shot to the bathroom.
