Alternatively, set aside one or two boxes of things that family might want that you can offer for anyone to go through....believe me, it will save you some grief in the long term with your family.  

Alternatively, you could use other assets as collateral

As an alternative, I am requesting contractors to sign hold harmless and release of liability agreements.  

In addition, as a learning experience they can try alternate rent models such as rent by room, STR, MTR. 

Are you just considering a bunch of alternatives?

In the alternative,  you can have a partnership agreement between your LLC and your partner.

If you are looking for more cost-effective options you can try roor.io or salesmate.io I have not used them yet but I am looking into them for alternate solutions.

I am looking for an alternative to Avail for lease signing and monthly rent collection for my 2 rental properties, and this company seems like it might be a winner.

fix-it-all (joint compound with some additives) is not suitable for exterior at allYes it will wick in water as the paint deteriorates, and cause more rot, and keeping a good coat of paint on it won't be enough long-term in many/most climates.bondo (polyester auto body resin) is a cheap-ish "alternative", although harder to get detail work just right and not really all that suitable anyway (maybe ok with a good epoxy / primer, perhaps?).

Usually the interest rate and points are a little higher up front than a traditional lender but it's a good alternative to bringing on a partner.
