Hi Luke,
It looks like you are in a great position to buy with 220k. You may have issues getting loans with conventional programs due to your mortgage as conventional looks at your personal DTI. With that being said, you credit score is very high, which would qualify you for business purpose programs like hard-money and rentals. The most common strategy here would be to do:
1. BRRRR - higher risk, but you can roll the cash over and over to scale quickly. You should be able to buy your second rental after 4-6 month after your first rental purchase. To lower your risk, you can opt for projects with less rehabs like cosmetic rehab.
2. DSCR Rental - lower risk, and you can use the 220k to even buy 2 rentals. If the value of the properties go up, you can also cash-out refinance and buy more rentals.
Ultimately, it's about preference and risk tolerance. Off course, there are many other strategies like house-hacking, STR, MTR, multi-family, flips and more.
