Non-deductible contributions can be made up to the plan limit.

If yes you may have to track the cash withdraw slip.

I am seeking some advice on withdrawing from my Roth TSP.

The moratorium you are referring to might be that they aren't raising their maximums for different unit types.Your justification for raising the rents needs to be that what they are currently paying isn't in-line with comparable units...they don't care about your expenses or that taxes have gone up, they care that what they are paying is comparable to the rest of your immediate market, and under the maximum limit.

When a party related to the transaction has more than one role in the transaction or is employed by or has an ownership interest in a company that is involved in the transaction (including but not limited to third parties such as marketing companies, builder / developer, broker, or realtor), there is a non-arm's length or at-interest risk.

@Adrian StamerI have limited investing experience in both markets.

You're limited by your income and what you have in cash for downpayment and post close.

I want to say screw it and continue do it all myself, but as you all know time is limited and having an extra hand is necessary. 

I have time to learn, but not time to learn before the red or green light decision on this one due to the upset bid period limits. 

My accounts aren't old enough t get approved for higher limits such as 25k and up.
