If you do not you will find money that is not accounted for.When you create an excel sheet, use two more columns:- type of account, income, expense, asset, liability or equity- property name.This way you will be able to filter all the data as needed and reconcile your bank statements. 

John, other than we know historically markets correct.. what are you seeing on the near horizon that would make a drastic market change in your area.. to me Ohio is finally digging out of being one of the hardest hit states in the country economically.. 

To find data regarding the current percentage breakdown of owners3.

It lets you filter data based on % vacancy, $ per unit, and shows properties not listed on loopnet, and more.

AirDNA (by far the most common way new people get their initial revenue projections) does include cleaning fees in revenue, so it is important those people are not misled away from calculating that into their expenses if they're using AirDNA data, or they could end up in real trouble from advice that didn't fully explain the context.

I still don't know how to best use the data tho...

@Ivan Luna On the market has some great data about markets that are doing well and holding strong in this environment.

@Joseph Eversman I grew up in those areas and lived in Morgantown WV and Pittsburgh through much of my 20s and 30s....my perception is that most of the areas you mentioned (south of Pittsburgh) have little appreciation (and risk of depreciation), so if your goal is long term appreciation, those markets probably won't perform very well. ....either way, you'll probably want to look into the relevant market data on appreciation, jobs, population, etc. to make sure......if you're willing to go as far south as WV, I'd suggest checking out Morgantown, or going north to Pittsburgh.

However, where do you find reliable contractors or brokers who can provide this type of data? 

As the others have said you have to reconstruct the operating statements and they are only as reliable as the available data.
