A persons ability to mange their own money before starting a business is a pretty good indication of how they will manage their businesses money. 

@Ron Manges Hey Ron!

Also I am not sure what amount of time that would take to mange, or the whole process of eviction for units when they do not pay. 

Found the deal manged the work and kept budget good and did some of the work What was the outcome?

@Heshel Mangel I been working with few brokers for some time in each of the cities in Ohio (Cincinnati, Columbus, Cleveland, Akron).

There are a lot of little things you can do to mange your business better.

My husband has been a realtor for seven years, we have couple of rental properties that we mange ourselves.

For some of them we handle the renovations and then mange the property too.

There are great apartment deals out there you just need to make sure the numbers make sense and it is a profitable deal duplexes are great to but I personally feel like it's just more potential in apartments and your return would be greater everything would be situated in one location although if you used financing on your deals you could get a substantial amount of duplex deals going and you could own some out right you would just have to look at then numbers and cash flows for instance would you be hiring a property manger to manage all those duplexes were as they could mange that apartment building 

That was before he left to start his own management business.He only manges larger 100+ unit complexes as far as I know but I am not sure.
