Probably 2-4 units, or converting a single-family into a multi-unit by adding an ADU or mother in law suite.

I'm trying to help my mother.

Much of that labor was child labor (or rather offspring labor--he is 18 now) and mother labor (she came over for a few hours on two days to clean and do little stuff to keep me company), but it's still a lot of time!

@Matthew Banghart I have been trying to get my mother to house hack in one of my vacants for years - no go yet.

Most of the remainder of the homeless are Single mothers with children.

My wife and I have now owned our current home for 15 months and I thought I'd do a deal recap.We purchased our current home (single family home with a mother-in-law suite in the basement) in March of 2020.

I am currently house hacking in Westminster CO and have a house where the basement has a 1,000 sq ft basement "mother-in-law" suite that has a lockable, entry door in the basement utility room. 

After spending half the morning of my closing locating the board president, going to his condo to get the board resolution, I'm glad I have it, and sent the PM a nasty reply via certified mail saying "here's a copy of the board resolution for unit xxx, and I'm surprised you lost track of such an important document".And we recently closed on my mother in laws estate, which includes a coop.

Instead, locate a SFH with a separate income sweet/ ADU/ Mother-in-law unit already built in the property.

Cash invested: $10,000 I inherited this property from my mother.
