@George Lods. I am going to give you a model that contradicts Greg S.
I own nothing but SFRs. I partnered on a 4plex. Great experience, but will never do it again. Although there are more doors, you can have more issues. And they usually involve tenants. It usually takes 2.5 out of 4 occupied to break even. Tenants, depending on the quality of 4plex you own, can come and go. You can go a significant amount of the year with an average of 3 out of 4 doors filled. Although you are making money, you are not making the money you envisioned for the hassles.
My business model relies on consistency. I buy SFR that are A or A- properties in good school districts. I do open houses where I have had up to 25 applications for a property. I choose my tenants, my tenants don't choose me.
The initial cap rates I get are a 'non-sexy' 4-6%, which most on BP would criticize. However, time is my ally and the cap rates usually go up quite quickly. I have a number of CAP rates in the low double digits (10-11%+) now and the values have appreciated as well. My AVERAGE stay is 3 years. I have had one tenant for 9 years. I only lose them if they transfer out of town OR buy their own place.
My former 4plex partner now has 22 MFH 'doors'. He does all the work himself, works his butt off AND has all the hassles I mentioned above. It really comes down to how much time do YOU want to work on the business.
The model I created was when I was an employee of Cisco Systems. I was flying around the country and sometimes around the world for my 8-5 job/career. I wanted to expand my real estate holdings, but needed to create scaleable systems that would allow me to do most things remotely OR have the tenant take care of problems that may arise. It is my belief that I could have up to 30 properties doing ALL the management work myself, and not be impacted significantly on my personal time.
My systems that I have created take about 15 minutes a MONTH to do my business. To be honest, I spend more time on excel spreadsheets for my CPA. ;-)
I have recently retired from the rat race, but I am still a rat. LOL.
Now you have both sides of the story. It will really depend on what type of business you want and how involved you want to be in it.
Kind Regards,
AG
