My PM used to use a software rentec, and rentec would give you a running tally of cash in/cash out across your whole portfolio. 

A displaced truck driver is not going to be a software engineer.

I have all the expenses in a different row with repairs at the bottom and a column for each property.There is software you can also use. 

SOFTWARES/TOOLS WE USE:Quickbooks (just changed from Stesa) - AccountingGmail / Google Drive - I create an email for the business and use this as a shared drive for all of my rental documentation.

However, this also puts me at risk of an audit. 

Within the IRS technical audit guide they specifically highlight being several hundred miles away from the property as a potential red flag. 

The SEC audit or a lawsuit will cost you a lot more money in the end. 

It is the most popular software in the industry and all CPAs know how to navigate it which is nice.

If you were audited and it was determined that you bent the rules for another renter, for any reason, at any time in the past, then FHA could ding you.

Airdna is your best place to gather actual numbers, although you do need to know how to use the software, as well as talking to neighbors in the same complex with a STR.
