I hope to utilize the rent hacking approach by buying a multifamily that I can live in and rent out the remaining units.

Lenders have the right to execute the Due on Sale Clause, but rarely do on a performing note in stable interest rate climates.As a conservative CPA investor I have not considered this approach, but real estate is risky and some investors like to push the risk and see what if anything happens. 

I have owned in the mid west and south for more than 10 years.. and have made literally thousands of loans from my first out of state loan in Detroit in 2001,, when turn key was a new fangled approach my LA based marketing guys were doing .YOu will need to really understand the socio demographics to understand were and how to invest in the mid west and south.I am pretty heavy in Charleston right now so I follow the news there  read this article..

Approach the situation nicely and offer to help her out - if she refuses you'll be left with no recourse but an eviction that will end up on her backround check therefore holding her back on future rentals. 

I am taking more of a "Lending Club" approach spreading the risk out over a lot of deals and like the comments in previous posts, I am depending heavily on the portals DD.

Also I want to start some different marketing approaches and other real estate strategies.

so say you approach a potential motivated seller to buy their house and relieve them of their financial issue (cant make payment, etc). 

And it sounds like the way you are approaching it is even better.. having ONE unit out of 4 as a vacation rental.

I'm currently looking at a coaching program to get trained and educated, and would be interested to hear about your situation and approach.

I'm definitely going to consider that approach as I think it may very well be the in-between answer I need.
