I found it researching online after many months.

However, if all they offer is general info, I think you can find most of it yourself in Bigger Pockets and other online sources.

The first apartments I rented as the owner, were previously rented by the former owner at $150 month including utilities. 

Need to watch out for utilities like water meter, electrical, gas, and sewer.

You need to work with a lender that will utilize STR 1007 Data and/or AirDNA Income on a REFI.Tough deal but we do this consistently.

@Kyle Trotman If you purchased with a hard money loan conventional lenders will require extensive seasoning to utilize the new appraised value for cash out. 

There's a few different ways to focus on a lower rate such as with house hacking and making the investment your primary residence, requesting a significant closing credit from the sellers for standard rate buy-downs (which I've had great success with recently), or utilizing lenders who offer short term rate lowering solutions such as 2-1 rate buy downs (again, ideally paid for by the sellers).

Just shop around online, look for properties similar to yours, add them to favorites and watch them to see how long it takes for them to rent.

Big Banks like Wells Fargo, BOA, Citi, US Bank, and Chase utilize lending programs aimed to service large swaths of depositors.

Seen that play a few times.. this whole sub to being taught to under capitalized or starter investors who don't know what they don't know and learn this on line is just so very dangerous.
