There are multiple customizations for STR that could be made. 

However, the fact that Rent to Retirement’s reviews keep coming back might also be a sign that they're hitting all the right notes with their customers.

I started by patching about a dozen (not small) holes in the wall, re-doing all the drywall in the bathroom, installing new shower plumbing, putting in recessed lighting, installing seamless LVP throughout, texturing/priming/painting all walls, installing new 5 inch pine baseboard all around, and installing custom bathroom vanity/pantry cabinets, and hanging new custom shaker doors in the kitchen.

My credit union I work with will allow 1.3 million in debt or 5 properties before they want one to incorporate.

And on the commercial build out do you believe this to be an attractive feature to the renters and their customers.

I have been working on customers homes doing painting and renovation for years. 

I personally do not touch equity in my own home to incorporate into my business.

I set an arbitrary goal of obtaining 10 reviews on Vrbo before incorporating Airbnb; however, this process took longer than anticipated, as only 77% of Vrbo guests left reviews.

One thing to consider since you are a California resident investing is the compliance requirements for LLCs incorporated in California or operating as a foreign entity here - the rules here are different than most states.  

I don't think we owe $800 in CA, we incorporated in GA and have a registered agent in GA. 2.
