We sold it as a fixer upper for about $25K. 

They qualified me for an upper tier program (maybe they tell everyone that :))  so rates/points were competitive, but they can't close in 2 weeks (they can, but you can't bank on it, they make you write contracts for 3 weeks).  

I do not have any experience in the real estate industry(software engineer by trade), but I'm willing to put in the leg work to learn what works and what doesn't.

I taught a class last week titled, "10 Types of Fixer Uppers That Don't Require Carpet and Paint!"  

You'll be able to defer federal however and that would create a net benefit as long as the 1031 didn't cost you an arm and a leg (figure 750 for one).  

There appear to be many fixer-upper type of homes in Arden-Arcade that might be perfect for the BRRRR strategy from Bigger Pockets.

I believe that would be considered an upper end home in that area, correct?

As it was coming time to pay off the credit card promo, I was also able to secure a deal for another fixer upper cabin for $35K but it needs 10-15K of work.

I believe if you can find a way to build trust with these people you will be able to get your entire leg in the door. 

We are considering doing this to gain capital to purchase a multifamily, and then house hack. and attempt to get a somewhat fixer upper and then BRRR it.
