My goal is to build a successful flipping business while keeping family time a top priority.

I completely agree that personal interaction can go a long way in building rapport with guests, especially when you're trying to create a memorable experience.

I've seen estimates of $200 to $400 per square foot for SoCal with $700 sq ft for something higher end and building up a hill and but possibly higher for San Francisco Bay Area (lhigher labor costs, etc.).  

Staying on the same page and building trust.

I began shopping for a large construction loan to build a new car wash on the land. 

When it comes to these types of auctions by the sheriff, is there a waiting period that must be observed before rehabbing/renting the building post winning the bid?

Build your team of players who are already performing the way you want to.

I just want some outside eyes to help me understand if this deal is what I should expect to find as I build my portfolio.I plan to buy and hold long term.

Glad you are setting aside money, but if the HVAC is 20 years old, or the septic system has never been pumped, or the roof is 25 years old, etc; you will get hit with a cost before your build up enough set aside.How stable is the other tenant?
