I'm not sure why you (the original poster, not Jaron) think there is a company out there that is going to give you free ACH without living off the float.

Real estate can be unpredictable at times and there is nothing like a war chest to allow you to float during tough markets or make acquisitions when financing is tight.

Thing is any "decent" GC must have the $-reserves to fully float at least 50% of his entire production jobs at any given time.

You're going to likely need a substantial down and be able to float the payments. 

I had heard this was being floated but didn't know it was being pushed so aggressively.

The fed is just increasing rates to pre-pandemic rates for now, 2019 was a solid year compared to 2018.we didn't have hyperinflation in the 2000s. peak inflation prior to the Great Recession was 4% floating between 2.5% and the high 3s averaging low 3s before 2007. the Fed target for economic growth of 2%.

The risk to investors with floating interest rates is very high if inflation continues upward.

You could try to extract equity in the form of a HELOC but that presents it's unique risks if you have a floating rate. 

So if your total loan amount is 150k let's say then you'll pay 1,500/month in holding costs, 3 payments min so that's 4,500 in holding costs maybe 6k if you go 4 months.So just to buy a distressed property for 100k and put 75k in it and hope to get 225k when you're done, you will need to float 35k. 

Given your involvement in different areas, consider checking out various property types – residential, commercial, whatever floats your boat.
