But Oklahoma on my list for sure 

I want to avoid falling into a mindset of thinking we can't afford to invest because of the needs in front of us.

It seems more your fault for choosing the "lying" contractors from the tenants point of view, if you ask them to pay up, I'm sure they would.

I am asking for any guidance on what else to look into for MTR to make sure this is the right decision for my mother-in-laws property.I appreciate your time reading my post and answering my questions!

Make sure to speak with the Title/Escrow officer directly to verify their wiring instructions to avoid being a victim of wire fraud.6. 

I like Warren Buffet's advice to make sure you understand the investment completely before investing.  

Just make sure you mention it in your listing description so expectations are met if they do need to access it!

I usually use a RE agent for sales, but I'm not sure how to pick one. 

THat we have seen (but you pay a hefty price to borrow for that type of thing) which is basically borrowing at credit card rates so you need to have a locked in buyer on the back end.Other option is an equity partner as you mention but lets say its worth $750k (not sure value) - maybe get someone to put in 25-50% max. but they will want a considerable portion of the upside and want to see a definitive exit strategy.

For sure you need a lender who understands them VERY well - try connecting with @Jose Valdovinos who is here in Chicago, but lends across the country!
