Hey Jennifer!
Debt service loans all the way for your situation. FICO is still a factor (yours is high enough that you shouldn't have any concerns here), but we don't look at employment history, income or DTI. Instead, lenders want to see that the property's income can cover (or exceed) the monthly principal, interest, taxes, insurance and HOA (if applicable). Based on the info in your post, as long as taxes and/or HOA aren't crazy high, you should be good!
Biggest downside with this type of loan is the prepayment penalty - PA is one of the weird states where some lenders make you "buy out" the penalty, meaning you'll have higher fees or a higher rate. Not all of them do though. Just something to be aware of. If you don't have to buy it out, 3-5 years is common and a sale OR refinance in that time will trigger the penalty. It's usually structured as a stepdown. For example, a 5 year PPP would be 5/4/3/2/1 - a 5% penalty in year 1, 4% in year 2, 3% in year 3, and so on.
Hopefully that helps, feel free to reach out if you have questions or need anything else!
