Umbrella insurance provides substantial liability protection at a lower cost and avoids the administrative complexities of managing an LLC.

I have some YouTube videos that may help with some of your questions and always happy to have a call to dive a little deeper. 1. which development(s) tends to be the best for ROI/have the best occupancy rates? 

Houses in my development have sold as high as 585k, my house was appraised for 475k as is.

As mentioned by @Chris Mason, Bridge Loans: These short-term loans can provide immediate financing until more traditional financing becomes available or until the property stabilizes and becomes more attractive to lenders.Interest rates and stipulations may be a pain.Out of the box here and requires a few more research, SBA Loans: Small Business Administration loans can be an option, especially the SBA 7(a) loan program, which can be used for hotel acquisitions.I heard someone  mention - Mezzanine Financing: it involves a combination of debt and equity financing, which might appeal to some investors looking for higher returns.

After years of experience, I developed a spreadsheet with key formulas and checklists to calculate the true Cash-on-Cash Return on Investment (CoC ROI). 

It is located in some of the newest developments on the north side of Katy, TX 77493 (I am not sure if I can post a link to the Zillow page or provide the address because I don't own it yet).

Would like to develope some multifamily soon.

I saw that the population grew by 5% from 2020 and I haven't seen much development as far as new housing goes so what could be causing this uptick in time on market? 

Seeking a construction/architect/development mentor would be wise.

The Greater Phx area also has more places to expand, but be cautious of "island" developments that are separated from bigger cities.
