I am looking for a RE financor/investor to lend me the amounted fix money we agree to buy the property for, and in exchange I will pay the investor a 6.3% interest by distributing monthly passive income to them in a duration of 15 years.Using the deal that I currently am seeking for now, This Fourplex is listed for $459,900. i plan to negiociate down to AT MOST $409,900 (50K less than asking price).

Real estate is an excellent avenue to help you achieve those goals, especially since it can create both passive income and long-term wealth.

Your cousin should contact the lender to discuss his options.If he rents it out, he must report rental income and expenses (e.g., mortgage interest, taxes, repairs, depreciation) on Schedule E starting when the property is placed in service.

If you want private investors, start by asking friends, family, or colleagues in your network who may wish to a passive income opportunity. 

DSCR Loan (10% Down Possible)Debt-Service Coverage Ratio (DSCR) loans are based on the rental income, not your personal income.Some lenders allow 10% down, though 15-20% is more common.6.

Lender does not look at your income, just your FICO and they want to see rental income.

And I would love some passive income or at least someone to pay my mortgage until we can pay it off maybe.
