The costs are far better where I would be investing than where I live and number still seem to make sense, even with factoring in 12% PM fees for them to advertise, rent, execute the lease, manage, pay bills and vacancy factoring.

when planning a purchase is there any way to factor in tax savings?

Then it clicked since there were no prorations factored in or settlement statement.    

I know the way to figuring that out is being able to read the numbers and factor the correct range of the estimated repair cost.

for me that number is $250 per door before factoring in property management. do you want a certain cash on cash return?

But I think the biggest driving factor right now, is the market.

A cost of a system may be $30k so you have to factor that in.

All 3 factors contribute to prices being lower.

Until you factor in the specific circumtances of the property.
