I recommend that you find a trusted or recommended Mortgage Loan Originator (MLO), who can give you options for property-based loans (mostly investment loans) and they don't use your taxes but the P&L of the property.

Raising money is all about marketing and sales (not real estate specific) so either hire marketing agency and read sales books, or hop on some LinkedIn courses on marketing and sales.Not sure the legal structure to use: talk to accountants and attorneys.Need deal flow: talk to brokers and go to a lot of networking events.Lending terms: start calling banks and loan brokers.From there, it is all risk mitigation. 

A better option if you can swing it is to purchase with your own funds, gain access, then refi into a loan.

I then found 3 properties from wholesalers in areas that I invest in regularly and purchased the properties with a hard money loan.

There is so much that goes into a successful STR beyond the very basics.Now, projections can help for people using a DSCR loan.

Financing might be a challenge.I would recommend consulting with a attorney, loan officer, and CPA to discuss your specific situation and determine the best course of action. 

@Kwanza P.Leveraged means using a loan (leverage) to buy the asset. 

Most people think real estate investing requires huge capital, perfect credit, or bank loans—but that’s not always true.

A foreclosure initiated by Ocwen won't touch your credit at all as you are in a second lien position and not a direct holder of the loan/mortgage.If the foreclosure starts you might be able to recoup the money or lose it.

You are going to want to find some good wholesalers in your area that can help you find distressed properties, or network/cold call some home/duplex owners in your area to see if you can find a discounted distressed properties, use the heloc to get hard money loan.
