Our contract is enforceable, and I can sue Don to force him make the payments that he agreed to make. 

I'd likely just agree to break the lease with a couple months of rent as a penalty rather than force these people to continue being tenants in my property....you never know what will happen to the condition of the property.

Do you think that is fair - to be forced to pay for your manager's mistake?

This could also force your current tenants to lose their jobs and need to move out and then you’d be in a real bind.

I was suggesting that if you wanted to do a 1031 of a property held in a LLC, they would be forced to also do the 1031 exchange.

(example - STR on the back end to increase cash flow)To me, forced apperception (BRRRR or buying at a discount) is a hedge against market corrections.

Sure, mortgage insurance eats into your cash flow a little bit if you're putting less than 20% down but in the scheme of things it's really not that much.Also, you won't have 20% equity in your property in a year assuming you put 10% down unless you are forcing appreciation or you somehow get some high market appreciation.

You should only consider switching when your current software has a significant flaw or lacks features that force you to spend excessive time on workarounds.

My clients can "force appreciate" the value of the property by doing a quality rehab for a lower than market cost because they are very good at spotting "diamonds in the rough".

They have no way to force removal, other than to pay off the loan on a home they no longer own.
