@Kevin Maldonado Great first post. Looks like you have been doing some research regarding rentals for sure. Here are my thoughts on you situation. First, I have a couple questions. How far away will your new house be? Are you planning on managing this property yourself? Do you make enough monthly income to cover your new mortgage and your current mortgage and still have enough to cover your bills? Is 800 your current insurance rate or is that an estimate for a landlord policy because usually they are significantly different. What does the HOA cover? You said that you were expecting to get a new roof for 5K. Isn't that covered in the HOA? How hot is the rental market in that area?
Regarding the numbers, it looks like you have a good grasp on the expenses. I think your maintenance budget of $400 is very low. I usually do 12% of rent but since this property is newer I might go down to 8%. The rest looks reasonable. If you refinanced before you moved to a 30 year mortgage I show a best case scenario cashflow (2200/month with 5% vacancy) of around $200 per month if you used a property manager. If you managed it yourself (easily doable unless you move far away) you are looking at almost $500 a month cashflow. Note I assumed 146k note on the refi to take into account that you will probably roll the closing costs into the refi.
Option 1. if you are really interested in getting into real estate some more, I might consider refi before moving to a 30yr at about 175k. That would give you 30k to put as a down payment for another rental. Even at 175k with 10% vacancy @ 2200 a month you are break even with a management company and positive cashflow of $275 per month if you manage yourself.
Option 2, if you make significant w-2 income, is to leave it as is and just rent it out. If you manage it yourself you should positive cashflow around $30 bucks a month but in 10ish years it will be paid off and your cashflow will go up significantly. I would not do this if your income was not significant to support issues or if you plan to move far away from the property. If you are wanting to be an absentee LL then you might want to sell and buy a cash flowing property out of state (maybe Texas :) ).
Personally I think if you want to be completely hands off, I would refi to 30 years at 146k and get a good property manager. If you want max cashflow, manage it yourself and refi to 30 year and start learning landlord laws :).
