@Rick Soto,Both options have their pros, but here’s a way to think about it given your plan to move in 5 years:Option 1 (10% DP, 2-1 Buydown): This gives you lower payments for the first two years and saves you cash flow short-term.

With loan extension you might have to come up with extra payment to get DSCR in range lender will approve.That is why to go through this exercise NOW and if you know tenant wants 300k TI to extend and bank wants 300k to pay down estimated balance when new loan placed you need 600k to come up with.

At $200k I'm guessing you would still cashflow even with such a small down payment. 

If this is financing for a stabilized property rate carries more importance but rate combined with origination fees, pre-payment penalty and term in which you intend on keeping the loan in place are all considerations which together should help in deciding the best financing option.

This gets my mortgage payment barely at break even for LTR value, (could be negative cash flowing), and lowers to about a 6% CoC (with down payment, renov and furnishings' costs)About 1.5 pt lower than my goal and with an MAO $10K higher than I wanted.b.

If someone is buying a $600k home, putting 10% down...their monthly payment would NOT be $3,000 per month.  

Predatory lease option investors know that and do that by design, they will keep the 5k-10k option payment after 12 months and lease/option it to the next family who is chasing after the American dream.

Brickell has that same kind of potential, but with even higher rent ceilings thanks to its location.A couple of things to keep in mind as you dive in:Financing: As a first-time buyer, you might qualify for low down payment programs.

A preforeclosure period of 120 days is required before a lender can enter foreclosure for lack of payment. 

Mortgage payment of $870 PITI with 20% down at a 7.25% investor rate.
