In theory this could go on forever, lol. 

The seller just factors the commission when setting the sale price.

Obviously lots of factors in this decision but I guess the basic question would be how much you value your time?

I have no exit strategy, plan is buy and hold forever...unless huge opportunity to add more doors in the future requires it.

I think the biggest factor we as agents need to focus on, is bringing value.

On this particular report I did factor that in, though I'm sure it's not the exact number.

We have bought tenanted properties and always strive to save a tenancy, rather than force a move.You've identified a key factor about low-income tenants.

Is there a situation where commercial properties may cashflow well and appreciate due to other factors?

....There are many factors that play into this obviously such as pay increases at my job, getting married etc. 

@Lucas Miller its not total to blame but its main factor, if the cost of the investment raises then something have to change. unless the investment become a better grade asset. like a market that is maturing and becoming Premium market like DFW for example, the base line of return is lower and will stay lower moving forward.
