But I do know that people often spend thousands on a beach house for the week, and depending on its proximity to the water, will pay even more. 

Borrowing the down payment from other people can be a powerful accelerating strategy.

Hey Alex, I'm interested in meeting other people in the ADU development space. 

I know people who invest in that area and do very well.

And I provide Rent to own homes for people with less -than perfect credit 

People tend to follow the money, but don't realize where they are in the curve.

(edit: the property can have up to 3 units built on it...house with attached separate apartment + unattached ADU)Of course, other people are telling me to park my cash in a high yield savings account and just chill LOL, but I'm not really comfortable with that either as an investment strategy.

People getting wise to wholesalers that will only close IF they can sell property for more than contract price, and use option period or weasel clause to terminate.  

Roam simply helps people find homes that have these types of loans.

There are always people who can rehab cheaper than you and have lower initial ROI requirements.
