We quickly realized that partnering was going to help us scale much much faster, and allow us the benefit to learn from their experience, as well as pick an choose what we liked from their processes/system of acquiring a large property and executing such as massive business plan.

Not so today, but not too far away either...The biggest differences:Conventional - typically a lower rate, no prepayment penalties, backed by the government or agency, DTI, Income, restrictions on property types, restrictions on # of properties owned, require passing AUS, can be difficult for Self-Employed, and heavy Underwriting guidelines.DSCR - higher rate (normally), prepayment penalties with various structures, backed by private investors or capital funds groups, about 1/3 of the paperwork, very laxed Underwriting guidelines, usually no restrictions on # of properties owned, no DTI calcs, no Income calcs, no massive amount of TRID disclosures, etc...Cost-wise (fees and such, not rate), they are very similar. 

Massive cash flow from 1 property and both my ADU builds broke even at 15 months.

The project had massive scope creep so it was difficult to pin him down on a final price when he was in the middle of working.

The investor is from Seattle (high priced market) and has created a massive net worth by only owning rent-by-the-room rentals to greatly increase cash flow. 

Considering the massive amount of debt that Federal and State governments are in, I expect taxes to be much higher by the time I'm old enough to withdraw from these types of accounts without penalty.

Flipping and wholesaling are just jobs unless you scale up massively and make it a business. 

We might see a massive default wave starting August, while the lending market is tightening up.

Typically, home sale prices will lag about a year or 2 behind the economic drop because a) there was a massive stimulus passed to help people ride this out in the short term and b) it takes a few missed months of mortgage payments before a bank will start foreclosure proceedings, which can take another 6-12 months. 

Gotta ask ya, and I'm not being a smart alec, but if the foundation slipped 2 inches in 47 years it may not be a massive hurdle unless you're seeking to make it perfect (or the cracks look brand new).
