If i purchase this HOA/COA lien i am wondering what are my options when it comes to the mortgage. i know there are 4 options for sure1) Notify the lender of the situation and payoff the mortgage2) Don't do anything, rent it out and let it get foreclosed on3) Flip the property quickly as possible before it gets foreclosed on (the mortgage will get paid off)4) Sell the property as is at a slight discount to recent comps (the mortgage will get paid off)This is the one I'm not so sure about5) Notify the lender of the situation and let me continue making the payments on the mortgage for a long term rental playmy question is, is #5 doable?

Even under this scenario, with a 50/50 split, you will not be getting paid for doing all the work.Another option would be for you to put in 50% of the purchase price using an LLC that you own 100%, borrow the remaining 50% from your investor as a 2nd position loan at a fair interest rate with points, and borrow the rehab under your personal guarantee.Better, if you can find a lender who will lend to a newbie, and they are out there, you could borrow the purchase money using some of your cash as a down payment, as well as all the rehab funds using a construction loan.

(Floating rate loans, with no rate cap) 

If the seller will entertain it you write it into your offer - what you're willing to pay total, loan term, interest rate, down payment.

Well, it's boring if you don't like scuba, snorkeling, boating, swimming, fishing, the Mayan ruins, Xcaret, riding around in golf carts, a marina, Dolphin Encounter, etc. in a very secure, safe environment that has a very low crime rate, and is constantly patrolled.

My mentor says you can get more cash flow and liquidity with SFH vs Multifamily, since brokers seem to want a certain cap rate on sales accross a geographic area vs when working with SFH sellers, they're more flexible and motivated based on individual needs.What are your thoughts on buying SFH vs Multifamily?

After being told there would be no pressure, on the second Zoom call she told us we had to sign up then by paying the $8K fee or risk losing a "$2K discount" and paying $10K later.

Last I did their rates were 1-2%. 

I can say that I never meet with sellers to tour properties because I'm selling at a healthy discount so I don't need to hold peoples hands through the process.
