Here is an associated review I wrote for them for reference to my experience:City Waterproofing is the definition of a family-run business that you can trust.

I know my taxes from the rental income on a personal level are deferred until retirement but is the unit subject to "business" income tax? 

I would suggest finding a local trusted broker or attorney who can advise on specifics for a fee.

It took some time, but I set everything up and executed a very large deal, I sold homes piece by piece and built my reputation as the kid you can trust.

They want me to upgrade to the next account level.

I agree with Marcus, you’ll definitely want to make sure you have boots on the ground that you can trust here and that understand the different neighborhoods, etc.

It will most likely be a line of credit with a second lien deed of trust (2nd mortgage).

The most important thing you need to do is call around now and find a general contractor that you like and trust, and more importantly, is willing to work with you on a 203k and is aware if the information that will need to be provided and that will provide that information in a timely manner. 

I write a deed of trust with myself or LLC (if it's one of my commercial properties) as mortgagor and the generic sounding s-corp I've had since 2003 as the mortgagee. 

Short term trading and refinancing RE is Expensive on multiple levels.
