Be sure to get up to speed on ADU laws and the opportunities. 

And how do you go by picking the out of state contractor and ensuring that the work that is being claimed as completed is indeed completed and to an acceptable quality. 

If I’m buying properties for long term buy and hold, and am buying quality properties with minimal/no rehab, and with little/no cashflow (buying for long term loan pay down, equity, and tax benefits), is it hard to get multiple mortgages?

Holding costs: 15,000 projecting 3-4 monthsADU: 200,000Total: 821,500ARV: 900,000-1.1MCash Flow: 2,944COC return 9.4% but thats with me in one of the units losing 2,000 in rents.prefabs are cheap and fast but still good quality.

People seem to measure your success/value/achievement with your house, and neighbor quality, to an extent, improves with house value.

As additional lots are purchased, the model can be duplicated to create multiple, quality communities.

For tenant screening, we want high quality person and can wait to get one, but is our criteria too strict:  740 credit score, 2 month sec deposit, 37% max debt/income ratio?

@Daniel Kevin LaraI rented by the room in my first house hack and basically just looked at comparable rents for entire units (similar property types, looking on Craigslist and Zillow for the most part) and divided by the number of rooms I was renting, then maybe adjust up or down based on the quality of your property.

Market comparables are important as we all know, but they can vary based on finishes and quality of work - so rather than just take the market estimate stated by zillow (as an example), I would ask a local realtor to provide a range of comps and then make sure as you renovating you're actually renovating with a house or two in mind.

My emphasis is much more heavy on the quality of neighborhood and the cashflow.Good luck!
