I bought 15 unit and have slowly crept up to 40-50 units. 

Perhaps the most consequential transaction involving creative financing solutions was a recent closing for a 20+ unit apartment complex in downtown Eugene. 

As for valuation, I see no reasons why a Junior ADU would negatively impact additional housing unit.

But, the self-sufficiency test for FHA loans can be really difficult in SF, meaning that the market rent from units you will not occupy must be sufficient to pay for the mortgage payment. 

what would you think of a 14,600sqft 3 unit property in sailboat bend, off market, that is RMM25 zoned and has a nice single family and duplex behind it, half of the lot if empty so it can be developed or RV/trailer parking, for $1.1M?

Hasabout 180 units, with ground for another 40.

Buffalo, New York, has once again been named the nation’s hottest housing market for 2025, marking the first time a city has held this title in consecutive years.

One-person rental units are in the highest demand, and co-living directly appeals to this market.

Even better if you buy 2-4 units, live in one and rent the rest - then repeat every 12 months.

@Charles Evans, definitely keep all paperwork associated with your tenant (lease, receipts, etc).For expenses that are not split per unit but are for the entire structure (utilities if not separately metered, mortgage interest, etc), keep a record of those payments so your tax pro can deduct a percentage of them for the unit you're renting.
