So far so good with the property, cash flowing and haven't experienced a vacancy yet but trying to prepare for the ups and downs.

I was considering a program where rent would go up $25 and they would get a $25 monthly "discount" to make payments online and on time. 

@Luka MilicevicI’ve read about people using programs to call multiple numbers at once to leave a mass voice mail.

I have heard of a lot of people that have experienced great success by setting up STRs near schools with football programs.

I've heard that investorfuse.com is a good program to use.

I've got a bunch of questions already prepared and a plan I would like to talk through based on my research. 

You have to refinance out of the VA, which means you will need 20% equity unless you qualify for another low down payment program.

You should look for a 4 plex because you can get the most bang for your buck doing that and you can do that by only putting 5% down OR using a Hard Money Lender that does a rental program for only 3 points down. 

I want to get an fha loan so I am able getting a duplex along with a downpayment assistance program that gives first time home owners with ( I believe ) a credit score of 640 they will give you 3.5% as a downpayment. 

Do it now so you are prepared to grow smoothly.
