If you are keeping the property this is an easy answer. You need a new 30 year loan. Rates right now are in the low 4's for investment property. A 4.25% 30 year fixed loan on a 109k balance reduces your PI payment to $536.21. That is almost $400 a month savings or just about 5k a year, that is a big deal...
If you have four or less properties the LTV will need to be 80, and if its been rented for the last 2 years you get to include all the rent in your income, less than 2 years you get to take 75% of the rent as income (this is for your DTI calculation and i'm pretty sure its 2 years, could just be 1 too).
And also, you need to drop the PM and manage it yourself. I have 8 doors that I self manage and i work a full time 40+ hour a week job. Its very easy, the amount of calls i get are maybe a half dozen a year. Majority of issues are either dead appliances (very easy fix, i love shopping), a leaky pipe/toilet/faucet, or a clogged drain. I'll try and fix most of them myself, but if i can't do it or i just don't want to, i'll just put a call into a local plumber and have them fix it. It can costs up to $180 for a leak\clog , but i only pay that $180 once. That PM fee you are paying,,, that's every month, for life. I never get when people tell me they have one rental in the same town they live in and they hire a property manager. You are giving away so much money for someone to collect YOUR check and call a plumber once a year.
