So far mostly people are telling me I'm probably stuck until their lease is over. meanwhile I also need to pay down my debt and improve credit score. 

For example a 25 y o applicant who has used credit minimally and has an unpaid bill of $50 in collections from when they switched phone carriers may have a low score, but the only negative on their credit is this one SMALL $50 debt.

If you take a loan to pay for your mother-in-law you are taking on that debt in your name.

In my case I sold off appreciated properties in a location I deemed as having limited future upside, and used the proceeds to eliminate all debt on the better located prime properties I wanted to keep long term.

But the answer for everyone may differ.Here are the personal attributes I see in those able to achieve a higher than market ROI, enough higher to be able to “scale”.1- Knowledge of real estate principles, real estate law and real estate finance2- Minimum 3 -5 years full time, or near full time experience directly related to real estate investing3- Ability to utilize technology for increased efficiency, capacity, and accuracy4- Excellent hired legal counsel and excellent hired marketing help5- Established method(s) of obtaining consistently high QUALITY deal flow6- Ability to manage and choose people who are NOT employees: Attorneys, Appraisers, Mortgage Brokers, Real Estate Brokers, Title Companies, Surveyors, Marketing Specialists, Accountants, Contractors, Consultants, Property Managers7- A VERIFIABLE track record of success8- Ability to identify, analyze, and negotiate a deal that can be “worked” for “enhanced” ROI9- Some type of competitive advantage; for example for me it’s my ability to analyze and identify mortgage loans that are actually less risky than all other lenders believe (on the investing in debt side), and on the real property side it’s my ability to analyze”pull the trigger” with LESS information than other investors need,  combined with the ability to pay cash, or raise significant capital almost instantly as well as being able to obtain loans at the lowest prime customer bank rate with no recourse or personal liability.  

If you want the least amount of paperwork, you could consider refinancing into a debt service loan.

Consider lease optioning the “now keeper” and walking the created debt forward if you lease option buyer can cash you out. 

And if they are in low value markets maybe they have zero debt..

When you can simply cooperate with me on seeing for housing assistance and have the US Federal Government pay for all of your rent debts?

Also, in order to get financing the lender wouldn’t allow SCI to dramatically overpay or they wouldn’t meet the debt service requirements.
