The ways that are alternatives to MLS can offer better returns but also a bit higher risk. 

Alternately, you could tell them they are permitted to do this now but that you may rescind permission later. 

If you can provide a reasonable alternative while waiting for repairs, that's all you need to do.

I have looked on Costar for individuals who have done 1031 Exchanges, peeped at alternative websites who act as either a brokerage or glorified listing service, called into my local networks, sifted through hedge fund managers, etc.  

There are literally dozens and dozens of much better areas nearby that will require you to beat off with a stick any other buyers and be able to buy in those alternative and superior areas in every way. 

I'm currently in a similar situation and I've started producing leads worth further exploration by finding them in alternative ways to the standard MLS listing.

Alternatively, you can just have a flat "utility" charge on their lease - that's what I do in these situations.Hope this helps!

That is not true self-direction, however many self-directed custodians deal exclusively in alternative investments.

Results will vary by loan type and lender.An alternative that may resolve your dilemma is the use of a SD401(K), which allows far greater tax deductions than a SEP and allow you multiple routes to use the funds for real estate investment.

Previous home equity in the form is cash provides me with alternatives, including remaining a renter if that's what I decide to do.
