Both units are approximately 400 sqft, "yurt-style" cabins with large decks.

I was kind of just checking my level.

It came out to $823 in expenses and in the area Section 8 is paying $11400 to $1600 a unit.

Personally, all of my units are full and have stayed full, no one is even late with rent much less behind, and no one is moving.

@Dmitriy Fomichenko scratch the part about being taxed at the capital gains rate, you’re right that it is taxed at income levels, however the rest stands.

If one or more units are vacant, the remaining units often don’t provide enough cash flow to cover expenses, making it harder to meet operating costs.Maintenance costs: A fourplex comes with four times the appliances, plumbing, HVAC systems, and other components to maintain, leading to significantly higher repair and maintenance expenses than single-family homes.If you want to see the detailed calculation, read this BP blog - More Units Doesn’t Mean More Money—Why a Single-Family Home Can Beat a Fourplex.Resale value: Multi-family properties have a limited buyer pool—mainly investors—who base their offers on CAP rates.

The only 110v dryers I see online are small portable units.

Even for a credit union that's pretty aggressive, and at a high level, seems like a great deal. 

However, in the case of a short term rental, it would depreciate over 39 years depending on if 20% or more of the units in the entire building are considered transient (rented for 30 days or less).

My rents are high at $6300 per 3BR unit so I guess the risk is if economy goes south and no one can afford the high rents.
