@Oleg Malkin, The 1031 exchange is used to track your tax deferral with the form 8824 that your accountant files in the year of your exchange. 

Any expense tracking you would recommend so I can be prepared tax time next year? 

Theoretically, we are on track to retire in our mid 50s. 

I've started doing some renovations on each property and have so far just ran everything through the 1 business credit card and business bank account -- keeping track of all of my invoices, etc.Even after I split up the properties into their own LLC's, is it safe to continue doing things this way?

Does anyone have a good spreadsheet template for tracking all expenses associated with rehabbing?

Most of these only allow in PM's with good track record and 50+ properties.

You will need 2 years of track history unless you have another job/someone else on the loan. 20K is not enough to start.

Plans start at just $59 per month, making it an attractive option for cost-conscious sellers.LendFoundry Loan Servicing Solution (LSS): This robust software offers features like loan tracking, repayment allocation, delinquency management, and investor reporting.

We use Appfolio in our office and love it, and I know there are people out there who use Turbo Tenant as well, I actually met their CEO at a conference and he was extremely knowledgeable of the struggle in keeping track of it all.
