I had to redo everything they did on my taxes. 

Thank you for that tip about meetups.

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 paid tax on it and mowed it about every 5 years so maybe put 10k into over the years.. deductive reasoning suggested city does not build and full blown interchange to go to nowhere. 

Does anyone have any tips/ advice to help make sure my property will appraise for what I planned on based on my rehab?

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.

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.

Of course SF’s über liberal city gov absolutely hates this phenomena, and activity taxes and limits new “market rate” housing in many different ways.

I have just read through the four years of this thread and found some great tips, thank you to the OP @Thomas Youngman and all the content others have provided.
