In most single family zoned areas adding a single ADU is not a value add meaning it will not add more value than the hands off cost of the addition.  

house hack in some sort of fashion.Either buy a duplex or large single family that you can rent out a room/side of the houseOr buy a fixer upper in the best neighborhood you can afford.

From there, you can move on to the BRRRR method with single-family homes—buying undervalued properties, rehabbing them, renting them out, and refinancing to pull out your investment for the next deal.

Another single family house had two front doors and they assumed it was 2 units, it was not. 

I was preapproved with that amount before, but it was for a single family, primary residence about six months ago.

Single family usually doesn't make much sense from a rent/price ratio in A-B areas unless you are doing a rehab.

Quote from @Luis Cerwin: I have a single family house in Detroit (I'm out of state) for past few years.

It’s clear that there’s an incredible wealth of knowledge and experience here, and I’m excited to continue learning and growing with this community.I’m looking to connect with members who are open to mentoring or collaborating on real estate deals, particularly in buy-and-hold strategies for single-family or multi-family properties.

Quote from @Zach Howard: Quote from @Jonathan Greene: If you are looking at properties in the US only on Zillow, and not seeing them in person (I know you are in Hong Kong), this is just an effort in futility because you can't underwrite single-family or small multifamily deals only online.
