I know that my COC my be lower, etc but my main concern since its my first property is being cash flow positive.  

The preliminary analysis can have lots of data, so it's important that the provider thoroughly review it with you to explain what depreciation tax deductions Cost Seg study provides and what depreciation benefit you would get w/o Cost Seg.

I sourced the property off market and secured seller financing, and I also self manage it as an Airbnb host with nothing but 5 star reviews.

That’s a problem if trying to enforce a security position as a lender or Noteholder.You may gain control but economics will dictate structuring a deal to pay the problem spouse something as a “lovely parting gift.” 

It also positions you to work more effectively with lenders and partners who want to see a professional financial setup.How are others here organizing their finances?

You can outsource and automate all you want but when you run into your guests in the driveway and they want to talk you can't just walk away....your reviews will reflect that.I used $1100 and $437 as a real example. 

If so, review it to ensure it matches the estoppel certificate4.

An LLC also makes refinancing in the BRRRR method smoother, as many lenders prefer loans through an entity for multi-property investors.Starting with the right structure positions you for long-term success.

We keep seeing conflicting views but my personal experience with buyers indicates that the outlook is positive.   

My position as GP is justified with work experience being that I invest and develop for years, and for putting the deal together and bringing the unique opportunity.
