@Berry Starnes, @Evan O'Brien Its really not a complicated process.Once you log on to your TSP account online; on the left tabs there is an option for TSP loan.

Read my Utilities 101 below to see some options.

Also, after a year, the mortgage hasn't been paid down by much, especially if it's a 30 year mortgage.The only challenge you may run into is if you purchased it using a low or no money down mortgage option like FHA or VA lending.

This reduces exit options and affects the value. 10) Small number of small units is the most expensive residential development there is.

Be sure to explore all around the forums as well as many of the FREE tools that Bigger Pockets provides.I am on the lending side of things and am always happy to hop on a call to discuss loan options that are out there, even if not offered by my resources.

However, there are better options than $180 a month and $1000 for a WP site. 

Would this be the ideal market, or are there other rental options we should explore? 

I can get prime-0.51% on a HELOC but I don't love the risk to my monthly payments if rates rise - that is why I like the fixed second mortgage option. 

This was very insightful and I will look into the options a bit further.

@Collin StewartSince you're PCSing to Columbia, SC, and have VA loan entitlement remaining, house hacking a small multifamily with a VA loan is a strong option since it requires zero down.
