Figure out ways to enforce rules to protect yourself and the other renters.

Quote from @Elwin Green: I seek financing options for the first and third Rs of my first BRRRR project.I have a 2BR house under contract, and have funds available to close (about $32K).Of course, the house needs the first R - Rehab.Is there a lender here who would lend $20K-$25K against a free and clear property for rehab that would raise its value from $34K to $72K (per an appraisal in January)?

@Charles Evans Zelle and Venmo do not provide the same protections as a third-party rent payment portal.

Getting an LLC in place from the start can provide peace of mind and give you a chance to familiarize yourself with the process before expanding your portfolio.

If real estate is involved, separating it into its own LLC before the sale can simplify the process and make it easier to leverage a 1031 exchange.This post does not create a CPA-Client relationship.

In smaller towns, I think it would be very difficult.

If you find your comps are 10 miles away in a different town, you've probably gone too far.To do automated comps is easy. 

It goes without saying that the recent and ongoing disasters in California are some of the most devastating and destructive in recent memory.

You can build the tool yourself but it will take time.
