Best bet is to come here and see how things are.

Your best bet if you want to know that is calling the Section 8 Housing Assistant assigned to your tenant and asking, they may be able to calculate what it would look like.

Johnny, I know exactly which lender your working with.I am going to tell you, there are better options.Look around a bit, That prepay is 5% fixed for 3 years.I wouldn't pay 22k to buy a rate down in a decreasing rate environment.A 7.75% on a 3,2,1 declining prepayment is a better bet. 

Odds are the drain line, condensate pump, putting down new riser blocks or mounting blocks, the whips and line sets, new disconnect box, new low and high voltage wiring aren't in your Google pricing.

Just like @Jason Wray said, finding a good agent or already knowing one is your best bet.

I run a call center for Real Estate where we call for investors and I can tell ya, your best bet with such limited time is cold calling targeted lists (high equity within your buy box) for 3-4 hrs every day.

If you have a rent property with good cashflow, odds are you are BETTER qualified for the next mortgage than if you sold the rent property.  

Unless your agent is affiliated with a small Firm or works in the same local office as the listing agent, the odds of them knowing each other and having already shared info about either party with each other are pretty slim.

You bet!

Your best bet right now is to live in it and enjoy it as your primary.
