Whether debt or equity partners, I think this strategy is an interesting and fun one.Do you by chance have any clue about how many JV partners you can have, or the legality on how to "ask, without advertising?"

@Willy A German 5-6 years ago my now Ex was a real estate agent and the mortgage broker she worked with knew about all sorts of mortgages that the banks did not and would get her clients into loans despite bad credit or debt or whatever.

Can I go ahead now and use cash to pay-off existing mortgage and NOT have to take on new debt?  Or

What is your name When do you need something Who will be living with you If you have a pet we don’t allow pets Are you currently renting and were How long have you lived there Can I ask why are you moving How much is current rent When I check with your landlord will I find out that your rent was paid on time Can I ask were are you currently employed and wereHow long have you worked there Can I ask how much you make How about spouse name and work and how long and incomeDo you have a car payment and how much Do you have cell phone and how much Other long term debt or student debtHow is your credit if I pull it upHave you ever been convicted of a felony Have you ever been evicted from a property When do you want to see the property. 

When you purchase a deal of that size, does the bank still give you non-recourse debt?  Or

Even if a creditor were to obtain a legal judgment against a judgment-proof person or entity, they would not be able to collect the debt because the debtor simply doesn't have the means to pay it back.

@Russell Brazil yes we do but not paid off, so either that debtors would be a 2nd mortgage or we just cash-out refi.

Again, as long as you can manage it very wisely and are not prone to credit card debt or have bad spending habits then I think its a great way.

Creditor or debtor attorneys cannot give you the names of their clients or people they are going after (even if public record).Title companies which have attorneys may be able to pull lists for you which could be helpful.

trusting Wikipedia:"Non-recourse debt or a non-recourse loan is a secured loan (debt) that is secured by a pledge of collateral, typically real property, but for which the borrower is not personally liable."
