Hello - good question! Always buy as many units as you can afford. By afford, I mean financially as well as maintenance-wise as well.
If you buy a second home for yourself, are you going to rent it out or just have it for your own use? If you rent it out, will you have a management company take care of it?
The more units you buy, the more "help" you have paying your mortgage, taxes, etc. However, the more units you own, the greater the maintenance.
some investors start with a duplex, live in one side, and rent the other. this is easier to manage as you are right there and can see what needs immediate attention. Then graduate to a 4-plex or greater. good luck. Kathleen Barnato,
