I appreciate it If you decide to approach your tenant about them purchasing the property I recommend you contact a mortgage broker first to let them know what you are considering  Your objective is to get an idea on what the potential rates they may charge your tenant when it's time to exercise the option to purchase. 

I would say the posts concerning the 1600 block of N 27th Street is a good case study of where NOT to buy if that's your objective.

Shorter-term holds provide a better vehicle for accomplishing those objectives.

You'd very likely have "objections" which you'd (and your counsel) need to work through with the Title company and seller.

It really depends on your goals and what the objective is with the funds afterwards 

@Christian LicataFirst, start off deciding what your objective is.  

Take a very objective look at your property first and foremost.

It's about partnerships and principles, not simply money

You need a working knowledge of real estate principles, real estate finance and real estate law.
