In summary, I am curious if this looks like a project others would take on, and I'd appreciate feedback on how I might refine my deal analysis or estimates.

Owned Car with $852 Monthly PaymentSince you've refinanced this loan to remove the borrower, the lender likely needs proof that this payment is no longer your obligation.

Let's say, 10% on average. 25% x (1-.1)= 22.5% average STR fee.Average those two, and you get a little less than 18%, so 15% seems like a "fair" fee

Looking at the pictures, it looks like a nice flip.

I'd like to do fix and flips full time but don't quite have the capital to do this from the start.

You had better be on call 24/7 as your tenants will likely rarely sleep and will be digging holes in the walls looking for FBI cameras and copper wire to sell!     

There's nothing like the present.

You gotta pick something up for like 100k cash that is worth 150k or more as-is and fixed up 300k+. 

Hey @Devin Bost, I would highly recommend a few things to help with this. 1) Have systems and processes lined out for any emergency you can think of.2) A spreadsheet of subcontractors/ vendors that could handle the situation that arises (plumbing leak, electric out somewhere, etc.)3) Your cleaning team and handy person should be utilized for some things.4) Something like Breezeway can give you 24/7 support around your property with a dedicated phone number line.

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.
