Age plays a huge factor when it comes to comps.

You can also usually use 110-120% of market rent if you do have rent verification.

If they used newer builds as comps, they may have adjusted downward for age even if your house is fully renovated.

I wish I had started at your age!

Condition, age, tenant profile, and location all have a big impact on the numbers.

But in general answer to your question (I'm in North Carolina, not South) - I have a provision in my lease that ALL person's age 18 or above (at the time of lease start or renewal) must have an application on file, that includes credit and criminal / background - and I have the right to an updated credit and background report from all adult residents prior to lease renewal.

I wish I would have started investing at your age.

For me a great wealth builder was (1) a DEFINED BENEFIT plan allowing me to defer tax on up to $350,000 per year at age 50 when I was in the highest tax bracket; and conversion to and into a ROTH 401k (all self directed) over a 5 year period at a lower bracket and a BIG discount for the non liquidity of my retirement portfolio investments.  

Underwriting & TimingNavy Fed underwriting can be stricter on income verification and may require additional documentation since the loan is riskier with no money down.Timelines vary, but expect 30–45 days to close if everything goes smoothly.4.
