As for bank rolls and receipts do I just ask for them.

Many lenders and mortgage banks have both a retail (consumer calls/meets with an employee directly, the bank/lender must bankroll all the time wasting) and a wholesale division (volume based, the broker's job is to do all the stuff that consumes time and resources).An entire trolling campaign happened a few years ago surrounding this, it was 2018 when rates had just reached a 7 year high.

Up until this point I've only been able to focus on one deal at a time but have done very well with ROI on each deal and have built up a decent bankroll. 

I'm not lucky, my poker and roulette bankrolls will back me up on that. 

Do you have a track record in wholesaling and you're just trying to scale, or would someone be bankrolling your entrance into the market?

. $5mm or more) bankroll.

I'm not looking at buying now, but I did want to start wrapping my mind around the ins and outs of buying, fixing, and selling in short durations.I know market influence on income is a difficult way to make a living, so my goal is to make a bankroll to be able to fund my first flip with straight cash. 

I know a brit who is getting bank rolled by a guyin Monaco(tax exile place in Europe) he makes 20% of the profit, what 20% of $5k....now that is crazy!!!!

The Wells Fargo program will allow you to do it, but it is very, very cumbersome.I would suggest trying to get a construction loan, where you'd be paying int only for the first six months, then the bank rolls it into a conventional investor loan.

A 5 year plan that starts with a 100k bank roll is a great place to begin.
