I'm trying to Figure out how to make this potential deal work.Seller wants to sell but not right away because they still use the house for some income.  The Mortgage is paid off. How can I strike a deal where they can...

It's growing like crazy!

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

I would never do it for any “buyer” putting down less than 25%.

It is supposed to be tenant is responsible for utilities.

So you need to ask yourself: is this something I want to do?  

Hey Themis, it sounds like you already have a solid foundation in real estate from working in the commercial industry, so it should be a pretty smooth transition into doing your own investments.I would put a lot of focus on building out your team of contractors.

.#1 NUMBERS GAME:  It's not easy.   

Educating yourself and networking is the perfect foundation for real estate success.What areas of real estate are you most interested in?

@Dhruv Patel I believe you are getting ahead of yourself....Where in the US are you all-in (land acquisition, soft costs, hard construction) on new construction multi-family for $100/ft.
