Deposit is practically evaporated already...Help

I've been to a landlord bootcamp run by Atty Tristan Pettit, who my usual, all purpose attorney AND another attorney I know who also practices general business related law both said is definitely the best LANDLORD'S attorney in town and the guy to call if you're in any sort of serious landlord/tenant dispute or any serious case related to being a landlord where the stakes are high enough to make darn sure you've got the best possible representation due to what you could lose if things go the wrong way!

@Nathan Galvan If this is going to be an investment I would start learning all you can about the numbers side of REI, and start practicing what will make sense when it comes to calculating costs.  

It's a different market one is about consistent cash flow and another is about speculating on appreciation.

I am a CPA, though non-practicing now, and invest in real estate in Houston.

Whatever you can get to make yourself feel safer in your future rent payments.If you will consistently issue 7-day default letters for all of your tenants when they are late, you will see timely rent payments improve. 

Loan payments are fixed payments consisting of interest and principalSolo 401k loan rules do not allow for Interest only payments or principal payments only.The maximum Solo 401k loan amount is either 50% of account balance or maximum amount of $50K.

She pays her rent late most months but pays consistently on the same day and pays the pretty hefty late fee so I haven't minded much as of yet.

If the first one does qualify, I return the app fees to any other parties- I feel like this is the right thing to do and would like to continue the practice.  

I consistently get calls from my previous mailers from a while ago.
