Owner financing makes sense when you have their credit report in hand.

On the other hand, you stated that the management firm was charging 15% and had a 15k expense. 

Rules/policies are subject to change and selling units in some buildings can be challenging.Condos, on the other hand, typically have more lenient rules/policies oftentimes allowing for unit owners to rent their apartments immediately and indefinitely.The rule flexibility, however, comes with a price.

Right now I am on the middle of a flip no more cash in hand to make an offer so my only option seems to be investors or a HELOC against my flip or my own house.

but there is case law that allows you to break some terms of a mortgage agreement if something is unenforceable, for example the sub-to community relies on the Supreme Court cases which say it's not required to notify the lender when you transfer the deed/title. 

If you win but the guest then appeals it, Vrbo washes their hands of it and you lose. 

Hey James, I'm sure you've found a solution by now considering this post is 2 years old, but for future reference here is what I have found as far as software solutions for managing a handful of rehab projects at once.Construction/Rehabbing Specific PM Software vs Generic PM SoftwaresWhen choosing your software solutions you will need to decide if you prefer a house flipping software that is specifically built for managing a house flipping business or use a generic project management software.  

And arguably I think most would prefer a management transfer period as well, I'd say 2yrs, because you've been self-operating so i don't want to fumble around int he dark to sort what "system" has been used.

The premise of the time value of money struck me: "Money in hand today has earning potential, and we can turn money today into more money tomorrow by investing it."

If you’re able to be hands-on, I’d recommend exploring local deals or those in your home market.
