@John Lasheri agree with you, you'd be surprised at how many people listen to Grant Cardone though, and decide that they're going to go buy a 100 unit with 'OPM' as their first deal and quit their job.i think buying something of that size with a few partners is a perfectly good goal. 

I here in the Netherlands Rotterdam working on renovating a 3 unit building

If multi-family is this 100 studios in a 50,000 SF building or 30 3 bedroom unit in the same square footage.

I'm interested in building 2-4 unit MF.

Lastly, check any shared doors or gaps and add door sweeps or weatherstripping to block sound from traveling between the units. 

Congrats @Emily Pena - I'm also an agent (working mostly with investors), property manager and an investor myself (currently owning 26 rental units). 

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. 

I recently purchased a 2 unit property as owner occupied with one unit already rented out. 3 months after closing, I was laid off due to a restructure at my company, so I decided to rent out the other unit my girlfriend and I planned to live in.

In Dayton, I find most of my clients like A/B class 1-4 units because they can actually cash flow AND be in great areas.
