You can't model the expenses precisely unless you have some super quality tenant on a big, stable project.

In response to your question, it is important to note, as Buffett is fond of saying, that it is better to be approximately right than precisely wrong.

I really have no idea.I know this is a difficult question to answer with precision, but I'm just looking for a ballpark idea from anyone who has been through this before. 

From tenant placement to property management.

Hello Junior Salters, your yellow letters should consist of a short precise message to your potential prospect.

Everything with turnkeys is done for you- rehabbing, tenant placement, and property management placement.

Okay, that helps, thanks...I've been assuming about $200K/sf, and just wanted to make sure that it's not closer to $400/sf...This isn't an investment (which is why precision isn't very important) -- a friend is planning to buy and renovate his personal residence, and he just wants to know about where his costs will be, to the nearest couple hundred thousand dollars...

I would not rely to much on rentometer or zillow for precise numbers.  

The entire list of plumbing fixes includes:replace tub drain (mechanism toast plus drain was handyman'd out of code)replace water heaterreplace slop sink faucetreplace 2 sink faucetsbring upstairs 1/2 bath vanity drain to code (straight drop and no vent)move gas range feed to original placement in the house (they had it where the fridge should be and the fridge was a huge french door deal where the eat in location should be)re-run gas feed to dryer (utility co capped the line back towards a main joint)That ends up to be way more than I originally thought but it could have been worse.We pulled up the kitchen floor since someone had put el cheapo vinyl faux laminate down (always a bad choice) on top of old linoleum.

It looks like it is a similar model except on a larger scale with precise rehab calculations.
