http://www.mass.gov/ago/docs/press/2015/tax-foreclosure-reform.pdfthis article is very informative: you can invest in tax deeds and foreclose on the owners.

Because that seller is counting on you to keep his house from foreclosure, or close in time for him to pay some pressing bills, or remove the emotional pain of dealing with a dead parent's house.

Louis, for example, I would be hard pressed to find any single family homes at or over $200,000 that would rent for anything near $2,000 a month.

I think if I really enjoyed what I do it would be much easier to get "stuck", but since I know there is more in store for me I continue to press on.

You will be hard pressed to get a FSBO buyer to provide a pre-qual.  

I will let it accumulate to the point the will be pressed to pay so that I get rid of them and maybe they lose their voucher. 

Without pressing on and learning from experience, idk if we can truly "define a criteria" for ourselves.

I suggest the books by NOLO Press.

They have pressed the rents they approve down below market and announced they will not accept any rent increases.  

If so, what date will they press to leave your property?
