I'm a relatively new investor so please take what I say as a grain of salt but it *potentially* could be worthwhile to refi in order to achieve more cash flow. You said you originally received a mort. for $125,000 at 5%. If that is truly the case, according to mortgage calculators your monthly P&I payments are probably around the $670/month. Now that you have over 80% LTV, you could potentially refinance out and reduce your monthly P&I payment.
Let's assume your condo still will only appraise for $125,000. 80% LTV of $125,000 puts you at a maximum Convention refinance loan of $100,000. Now let's say you can get a conventional loan for $100,000 with an interest rate of 5.25%, your monthly P&I would reduce and now be around $552. Even though your interest rate went up, your monthly payment went down by $118 because the entire loan is based off a lesser amount. You'll now have an extra $118/month of cash flow which you could use to help pay the loan even further ahead.
There are a lot of IFS in this scenario so just make sure you run the numbers. What happens if the loan interest rate is higher? What happens if the condo appraises for less? Also, just know by refinancing it will cost $$ for closing costs so make sure to include that into your calculations.
