There are plenty of podcasts, books, and YouTube videos going through this in detail.

What is your ideal timeframe for this flip? 

Relationship with wholesalers will come along the way but in this current market inventory is so tight, everything sells (sometimes over market) so the timing is not ideal to target Wholesalers as your only source of deals. 

I've been reading and watching videos like crazy over the past year and have learned an amazing amount of information and must say THANK YOU!

It seems that you're right in an RV not being an ideal fit for your family's size, so I too would scrap that thought.

I am learning so much right now can't get enough of the BP podcasts and videos and love practicing and analyzing deals!

After my initial research, I think I might want to try looking into a rehab/flip or rehab/rent (buying fixer uppers in established neighborhoods, ideally where I can eventually build an ADU on the lot,) and down the line move towards lots zoned for multifamily properties on large lots (to maximize the real estate, or have off half the lot and build another dwelling on the new lot.) 

I always thought that "syndicating" meant finding equity partners.Going to a bank would be ideal, but if that option is not available for some reason. 

My CPA advised me that S-Corp’s are not ideal for real estate.

I'm thinking a med student in a 3 year residency would be ideal.
