In March spring break season begins, but I've found over the years that the first week of March most often does not rent, and the second week is iffy.

It's an attractive market because the Jun - Aug summer season is just as big as ski season. 

I'd work on maximizing my time and becoming a seasoned experienced pro before I even thought about quitting my W2. 

I have a seasoned GC relationship and am looking to fix and flip 10 - 20 houses in 2022. 

The only direct lenders I'd tried to work with early on were confused about how my investment fit into seasoning laws and erred on the side of extreme caution which also would have taken many months for a deal that didn't require any seasoning (which other lenders later confirmed). 

Cash out refi usually requires a seasoning period (eg. 1 year before you can refi) but can vary lender to lender

You season it for around 90 days and you as the owner sell the property.

if I borrow 100k for a BRRRR (purchase plus rehab) and borrow the money for 9 months (purchase and 6 month seasoning before cash-out refi) he is totally fine with me giving him a lump sum after 9 months of $105,941. 

Like Erik said, its pretty difficult to bypass the seasoning period, and quite frankly you benefit more from the seasoning period than without.

As far as buying the home under DSCR it can only be used as an investment and not a primary home.The seller cannot gift you or pay your down payment because the banks will "Source & Season" the funds.
