My husband was with the military, and we have a lot of military friends who just buy wherever they ago (each duty station is only around 2-3 yr) and they end up accumulating a lot of wealth/equity. 

Thanks Nicholas - the funding isn't really the main issue, as I could really pay cash if I wanted to.

@Dwayne Clarke going to take an educated guess that what you were cautioned about is buying someone else's problem.Over the last couple of years, many OOS investors bought a bunch of SFR and MFR properties with LITTLE due diligence.Many were sold Class C & D properties that they thought, or expected to perform like, were Class A or B.Once they figured out what the properties really were - via tenant nonperformance and never-ending maintenance issues, they looked to sell them.If you know what you are doing, their loss can be your gain.If you are new and do NOT know what you are doing, then you'll just be the next "sucker" that gets taken.

Monthly New Job market numbers are initially released high and revised down a few months later to camouflage the issue.

They have picked the best companies to integrate with and we haven't had any issues! 

I don’t know anything about TN real estate but NV real estate will perform better than most of TX with much lower property taxes, zero foundation issues, and cheaper insurance. 

Also, a 3-month try before you lease may be the issue, tenants are using it as an MTR, it gives them far too much wiggle room, and that short-term turnover can start hitting you in the pockets pretty hard...With that said some incentives you can offer are the first and last months rent-free for a 12-month lease.

After a couple of months of trying to resolve the issue I requested my money back for the printing and the money ($5600.00) I spent on mailings.  

Price, Condition, and Exposure it sounds like you have already done a reasonable amount on the exposure front so the main issues lies with either price and/or condition.

I would ideally not house hack this property and maybe leave all the tenants in place but what unforeseen issues can possibly come up.?
