Many may not require anything for a cosmetic flip, but if they do it may impact the timelineScheduling the trades- In your 2000 square foot example property we would schedule a majority of the trades in a serial fashion, not simultaneously.  

Usually the more doors per apartment building and/or the more money you put down, the more cash flow per door.You could also look into buying businesses (owning them, not running them), good old fashioned stock market investing (not retirement accounts, im talking brokerage accounts so you can actually use the moeny before retirement age) , cryptocurrency investing, or a mixture of all of them. 

If you do wholesale, it's best to be prepared should you not be able to resell to an end buyer in a timely fashion.

So I went back to the old fashioned way.  

Each assignment should be recorded, but this is not always done in a timely fashion, especially when someone purchases a note and sells it to someone else in a short period of time.

One thing to keep in mind as well though is that fashions in interior design do change.

I’m also a fashion designer and like to take some of those elements and apply it to real estate.

My mom and brother live with me right now, I plan on renting them my first property, we have talked and discussed this plenty of times, my mother is old fashioned, pays cash for everything, no credit  at all.

"Wholesaler","Rehabber", "Landlord" or "Retail Buyers" can safely be considered as "getting financing in some fashion."

The people I have used in the past have moved on in one fashion or another.
