But, he didn't have alot of information on the major cap ex info like roof age, HVAC, etc.

Two big rules of thumb:Generally speaking, the more square the house, the cheaper to frame and roof.  

Now obviously I know that a roof/furnace would alter this number, but overall it's a huge gain.401(k):Now assume that I take that same $18,000 that I used for the rental property but instead max out my 401(k).

New kitchen, new floors,roof, paint, etc.

Hey guys,So I found this triplex that is on the market for $290,000, the seller has redone the dry wall, roof and windows.

@Peter Padalino - couple suggestions, as I've been in your shoes.  1) Go crazy on energy efficient items - all LED bulbs, NEST or EcoBee thermostat, etc, etc.  2) Get someone to quote solar power for the roof if you have APS - I went solar and LOVE IT for rentals. 

Some people also include Capital Expenditure or CapEx expenses in their monthly calculations as well (which means the cost of big-ticket items like a new boiler or new roof).

The other might be due to a clogged gutter that cause water to overflow back to the roof and down the wall.

It was an underground house (see photo) and we have gutted it, torn off the old roof, and next week we start framing the new house on top.

I also saw your profile and I need a roofing contractor so please pm me for future projects.
