Are there investors here in Texas that have utilized and would recommend banks they hold series LLC accounts with? 

I just paid off my last utility bill.

Also I am thinking now that these are small rural counties with population in the entire county probably no more than 50k or so.. at least with most of those folks living in the city of Oroville which is right on the border with British Columbia In my flying days I would go into Oroville to get through US customs compared to going into one of the airports Airports north of Seattle .

Roku now has automatic account linking as of last year, a large portion of channels utilize this feature.

I would say don't be afraid to utilize the equity line again.

I used to ask the customer to provide me with a SOW.

If you use different sources it will be difficult to calibrate the different scores, but think of it as a percentage of the max available score.This particular score seems to be based on an applicant's credit history, including payment history, credit utilization, and credit availability. 

How are the utilities billed?

Probably will never be utilities there like electric or water. 

It's cool to know how to use tools to a do analysis but it has to be utilized properly.I have seen several flippers who have read Rich Dad Poor Dad; had every Performa, chart, analysis package, market analysis reports, cost benefit analysis, work break down structures, IMS and much more and botched every project.
