I half predict possible class action stuff once a same attorney gets wind of the multiples. 

You have multiple properties in a great market that are wonderfully placed for appreciation in the future.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

As an investor, I’ve had multiple sellers try to get out of an agreement after we had a legally executed mutually agreed upon sales/purchase agreement.

As far as I know, I don't think software like Stessa or Baselane can really track anything related to multiple owners/partners. 

Typically lenders divide up credit scores in multiple buckets with 780+ getting the best rate for some lenders while others it's 720, 740 or 760 gets the best rate pricing.

We've done this multiple times and it should not be a costly endeavor. 

In that situation I purchased a SF property 4 hours away from me this year as a fix-n-flip and to test the hypothesis that long distance fix-n-flips could be viable investments. 

The no is a test to see how they will take it and respond, whether they will listen.

I have turned over all of units multiple times the highest vacancy I'll get us under 1 week becuase property will be up for rent 2 months prior from existing tenants moving out.
