Do ya'll have flooring installation ideas, tips, warnings, or advice for me here?  

Any advice or tips or knowledge about the houston area market would be greatly appreciated!

I have a master "Rent Paid Checklist" for every month on Google sheets and Rent Rolls, a master Lease Anniversary List, and a monthly to-do list to make sure I don't forget to pay the mortgagees and such alongside a month-specific to-do list I add on to not forget to pay taxes or that Suite 205 said they are moving out at the end of the month.

Looking at the tax appraisals? 

I can think of mortgage, taxes, insurance, STR insurance, water/sewer, electricity, trash, internet/cable, cleaning (can pass through), supplies, and software.

Also, do you know if they verify the previous LL is actually the true owner of the property via tax or other records?  

I learned how to prepare all my tax returns, and realized it is better done by a professional who can keep up with the changes in tax law.

In terms of tax implications how does that even work?

Although with tax write-offs, depreciation, and equity growth, this property is still a positive of $15-$20K annually to our net worth.

Remember you're also paying 10% interest, taxes, insurance on that time.
