I've been told by some "old-timers" that military towns are fairly insulated from macroeconomic factors, particularly in lower-priced markets like Augusta, GA. 

I'm going to go to my credit union and talk to their loan officer to get as many answers as I can, but I'm still at the point where I don't know what I don't know, so I'm hoping that some of you can provide me with questions or situations to ask the lender about that I may not know to ask. 

I own 1 unit in a 6 units building in Union City, NJ. 

So far i've checked with multiple banks and credit unions and found nothing. 

Inspirational every time.If you haven't already, I would recommend that you start talking to lenders (banks, mortgage brokers, credit unions, etc.)

This is my first real estate property, but it's older and the loan amount is small (less than $200k), so the banks and credit unions I shopped around at are asking for higher interest rates.

I'm active duty military and I bought a primary residence in Dec 2017.

Kudos to you for putting together a real estate investment plan - and don't worry about your newbie status - spring chickens are overrated ;)If you haven't already, I would recommend that you start talking to potential lenders (banks, mortgage brokers, credit unions, etc.)

Its like a plumber...some are part of the plumbers union, but you dont need to be a union member to be a plumber.An agent, or sales person is licensed to sell real estate.

So glad you've already plugged into the Bigger Pockets podcast - that was a huge source of education for me when I first started.If you haven't already, I would recommend finding a real estate agent that you trust, and also start talking to lenders (banks, mortgage brokers, credit unions, etc.)
