There's a reason that most real estate partnerships and syndications look relatively similar, with the differences typically being the economics and control.You'll first need to decide whether you are looking to raise debt or equity.

The heirs can keep or sell the property for 95% of the appraised value to pay off the debt or they can sign the property over to the bank.

Also, this can negatively affect your ability/chances to finance/refi other projects in the near future because your debt-to-income ratio might be too high (although this can be solved with more rental income, so this is also a short/medium term problem).Another idea is if you have credit card debt or any other debt that is more expensive, then this can be a way to save on interest payments. 

Here's the refi question: Would you refinance at 75% LTV to get cash out which will mean a negative cash flow (negative for me means a big bite out of my 15% of rent set aside for vacancy/CapX/repairs) and pay the unsecured debt, OR would you refinance at rate and term which is almost break even income/expenses (for 2022) and pay the unsecured, even higher interest debt out of pocket.

You would have to have an income that can support the loans, rents that will help eat up some of the debt, or a great relationship with a lender. 

Once a BK13 has been approved, a trustee disburses payments and they are pretty strict about making the debtor pay the debts. 

If I have a cosigner then I will get the funding in his name and Payoff the debt or you can get HELOC for your existing property.

A cash-out refi may also make sense if you have credit card debt or other high-interest debt and could pay 3% using a cash-out refi.

I was hoping to house hack here in California 92507 (zipcode) Here's a quick summary of my situation:recent college graduate ( BUT with my major I still need to take 1 year internship to be able to qualify to take the board exam and get  licensed )  works part time (36 hours a week) - looking for a full-time position now since I graduatedsavings of 35k (worked while attending university)no student debt or debt at all If I was to house hack, to find a lender-- I have no one to co-sign with me -- would that be a problem?

I know hard money is common for flips and cash deals, but this would be more of a buy and hold investment for me and my debt or equity investors.SO the question to those who have bought 3-4 unit deals with investors, do you have a favorite between the two approaches?
