Generally speaking, with SFR or small multis, I just rely on the lease/rent roll (and some form of proof of payment; i.e. bank statements, deposit receipts, tax returns, etc.). 

I had to redo everything they did on my taxes. 

To succeed, focus on properties in high-demand neighborhoods like Pecan Grove or Aliana, and ensure your cash flow analysis accounts for high property taxes, potential HOA restrictions, and flood insurance costs.

You'll want to put together a personal financial statement (basically lists of all your assets and liabilities) and have your tax returns ready.

Property taxes are also insane.

This is obviously much better than $1,400 per month.On top of that, you will now get 2x the depreciation write-off so your taxes should go down.On top of that, you will now get 2x the appreciation when real estate price go up.On top of that, your tenants are helping you pay down the loan, initially at about $100/mo for both properties, which gradually gets better and better.On top of that, you now have more units so if one or two goes vacant, you have more renters covering the losses of the vacant units.If you want to keep these properties, I would do a cash-out refi and go buy more rental real estate.

Zero capital gain tax, next to zero income tax, property Tax is super small.  

First, there are about 6 states that I refuse to invest in because of their tax laws and what I consider to be an unfriendly business environment.

If you need financial help, ask under the "Finance, Tax, and Legal" forum.

And you would get to indefinitely defer all tax on the gain from the sale.
