So altogether,  I spent $60k on maintenance on the 3 duplexes,  that includes appliances, windows, and even a roof replacement.

The one thing most people don't realize is that the 1hr wall need to extend the from the ground to roof.

We are evaluating conversion of our Condo Association in NV to an Townhouse Association. the condo buildings share roofs and vertical walls i.e. they are attached side by side.

From roof leaks to sewage back ups.

Need costs: for rehab (roof plumbing electrical...), security cameras, track remote employees (they will steal the cash), cost to install pumps, license fees, hard equipment needed- registers, apps to run the register information, accounting, legal, cases for merchandise, shelves, door hardware, heater or HVAC depending on location...This is a tiny community there won't be a local plumber and electrician... add some cost for time to contact your team and travel will make any repairs more expensive.

It took us about 2.5 months to renovate the entire property including all the old systems (HVAC, Plumbing, electrical and roof along with everything else). 

Its completely hands-off (other than monitoring your account), very liquid, no additional expenses (like a leaking toilet, new roof, new flooring, etc.), and not deferred tax liability (which automaticlaly happens with a rentla).Oh, and you still get a step up in basis --- don't know why it keep being sold "as-if" real estate is the only asset that gets a step in basis on death... 

Recently I had one that cost $500, but that involved some extra work to re-pipe and add ventilation through the roof. 

The seller has replaced the roof last year.

Year of update of the systems (roof, plumbing, electric, heat)4. any pets, pools, tranpolines, or business use at any locationThey will usually need more specifics but this is a good start.
