As for your scenario, how many bedrooms would be ideal?

Ideally, you layout all the duties (Find, Underwrite, fund, rehab, manage) and assign a value to each of those based on how much time they might take. 

Quote from @Miguel Del Mazo: Knowing more about the area, it sounds like you'll have an ideal avatar of wealthy, young and trendy professionals that aren't ready for or looking for a home to own.

In playing with the numbers a bit, I'm seeing a trend of atleast 2% rent to price and (ideally) < 7% mortgage rate needed to achieve a decent cash on cash rate.

Private lenders often offer more creative solutions, like interest-only payments or custom timelines, which can be a game-changer if you’re working on a unique project.

That is less than ideal in some ways as well. 5.

I need to source the data myself, run the numbers, check the calculations, eventually build my own custom spreadsheet etc.

Ideally, we'd like to acquire one or two duplexes that meet the 1% rule and provide us with $1,000–$2,000 USD per month after property management fees and other expenses.
