Any repair, maintenance, or upkeep costs that are directly attributed to the rental property can be deducted on Schedule E.  

Mine charges about $600 a year, though only a portion of that can be attributed to real estate.Lengthy, messy evictions.

But, don't attribute too much weight to the whole 2% thing...consider it a wish list goal...

I've logged countless miles in my personal vehicle that could be attributed to the house, but its not even worth trying to quantify (never mind create a paper trail).

Let's say you have a spreadsheet with 300 home on it.Is there a place one can upload a, say a CSV file, and it returns the estimated home values, and maybe other attributes like square footage, for each listed address?

I’m going to attribute this to my screening and my no bs policies.

Your property is part personal residence and part investment property.Therefore - You are entitled to report expenses that are directly related to the investment property(repairs to rental units, cleaning rental units, advertising, etc) and expenses indirectly related to the investment property(mortgage interest, taxes, utilities(if it covers full property), trash collection etc.).You are also entitled to take an itemized deduction for mortgage interest and real estate taxes attributable to your unit.Also on the saleThe portion of your home used as a personal residence is able to exclude $250,000($500,000 if Married filing joint) of gain.The portion of your home used as an investment property is able to be exchanged for another investment property.

@Nathan Asher RobsonLocation, area school performance, property attributes, renovation work, neighborhood crime to name a few.

So, no, I will not stop using real estate trends, facts, and data in my modeling because my models have helped me analyze my markets. 16 primary attributes in 434,294 records represent my main market, and with that data I feel I have a handle on where OOS investors are, where flippers play, where turnover is highest, where I can find opportunity and trends, today and tomorrow.

This allows investors to take a significant passive loss and one of the most attractive attributes is time.
