This is part of the "due diligence" period, and it is so important.My advice would be to figure out the demand in the area for larger spaces.  

The larger wire is so much harder to deal with than the smaller service wire. 

Houston is so big - do you have an area you like or is local to you?

Several things to consider: 1) One of the main purposes of segmenting your assets into separate LLC's is so that your personal net worth or equity in other business ventures or properties isn't exposed, so unless you have a high net worth or a lot of equity in a property, it might not be worth bothering going the separate LLC route, especially when it restricts your financing of the property.  2) Most any commercial financing you get from a local bank for a small property is going to have recourse anyhow and require that you sign a personal guarantee, so you're still personally on the hook to the bank even in the case of a commercial loan.  3) If you're a newer investor and buying a deal that's tight on cash flow, or if you don't have a ton of cash sitting in the bank already, your greatest risk factor as an investor is your investment failing economically due to poor financing terms or not operating the investment properly, not because you get sued.

Be very careful when it comes to vacation homes you need to be very experienced to be able to calculate the exact net cash flow. there is so many expenses that you might not understand, in other words you need to do your homework before touching any vacation rentals especially with the pandemic .

We’re upfront with sellers, letting them know we have no intention of buying the house ourselves but instead plan to wholesale it.This approach of honesty is so remarkably effective that we often don’t mention wholesaling until we've made the decision to wholesale rather than buy the property and flip it.What many wholesalers don’t realize is that by embracing honesty and transparency, success becomes exponentially easier and faster than by resorting to deception.With transparency, there’s no need to hide or pretend.

Our electricity bill went from $4100 / year to $833/year (with added 2 EVs)With that being said, to answer the question of ROI, it is SO dependent on your usage and local pricing scheme, and you really have to do your own homework to dial in the right system set up to achieve the optimal results.

I still think it's much better than Hostaway, but there is so much I still can't do with Guesty. 

I mean the number of houses you'd need that even purely cashflow, say $500/mo is so many that quitting the W2 makes zero sense for 99.9% of people.
