@Jim Glover, many good answers here. But it all comes down to what you want and how active you wish to be in managing these properties.
If you plan to personally manage and maintain the MF, then yes it could be more headaches. However, if you leverage the benefits of scale, it will allow you to get professional property managers for a more reasonable rate than SFR and you can higher dedicate leasing and maintenance.
This is why I moved away from SFR rentals and flips to MF and now only invest in a min 125-150 units because of what I mentioned above.
Again, there are many ways to make money in real estate including SFRs.
Couple personal experiences I had in SFR which may be mitigated by MF:
- Tenant turnovers generally mean 8-10% vacancy. I have had tenant turnovers take 1 - 8 months in this market. The 8 months is extreme, but it can happen. Ultimately made it a flip and sold for a $100k profit.
- I had a tenant who trashed a nice SFR causing about $25k in damage. Got a judgement against them but good luck collecting. That was the last straw. I also have good tenants but one bad apple can have a bigger impact on an SFR, I think.
- Maintenance - roofs etc are more for a single-family per unit than a larger MF building which has 8-12 units in a typical garden-style apartment.
Again, neither of these are totally hands-free operations unless you want to invest as a Limited Partner in someone else's deal, just slightly different headaches ;-)
