Aaron Ruiz,
Moving above duplexes was an eye opener for me. Granted, besides a few duplexes I only have 1 x 4-family and 1x 3-family so I'm hardly an expert, but here are a couple of my lessons learned with regards to 4-plexes:
- If possible, assign parking spaces and make sure everyone knows the plan. Same with porches, patios, etc. I include a property diagram as an addendum to the lease which outlines sole-use areas and common use areas. This diagram has stopped more arguements than I can count.
- Provide some type of storage/area for bikes, lawn chairs, etc. 4 families worth of outside "stuff" will quickly make your property look like a flea market if you don't give tenants someplace to put their things. Once you assign the storage, then enforce it.
- If you pay water/sewer or any other utilities, get a handle on it quickly. Your water bill will go through the roof in a 4-unit if every family is setting up wading pools (I don't allow pools [ utility cost, liability and health/safety].)
- Figure out which tenant you can count on and cultivate a relationship so that he/she becomes your eyes and ears on the property. Not a narc, but someone who is interest in keeping it a nice place to live.
- Try to keep similar rent for similar units. Nothing upsets the delicate balance of multi-family living than when tenants find out that the folks in Apartment A pay $50 a month less than they do.
- Your biggest enemy in 4-units will be turn-over. Little things make a big difference and go a long way to making tenants comfortable and less willing to move. A security light in the parking area; a clean laundry area; new mailboxes ... all speak to your interest in the tenants and, over the long-term, will pay for themselves many times over in lower churn and reduced expenses.
There are plenty of others ideas, but these are the ones that come to mind right now.
Good luck,
Sam
