In an apartment it is more common for tenants to pay electric only.

Also in NC my costs are ~$4k per year to be actively licensed and pay all dues, MLS fees, etc.My $0.02 is there are a million questions people try to wade through before buying their first deal and it tends to prevent action (not saying that is the case, but it very common for people). 

Also, for being a "General Contractor", a fee of 15% plus or minus 5% is fairly common in my opinion.

Thanks for mentioning the second/vacation home loan I'm sure these are common in places like FL.

Then see if there are enough commonalities, if the chemistry is right, then call the product lines and ask a lot of questions once you have the right details.

This is a common problem that happens with Fix n Flippers -- if it doesn't sell in the anticipated time frame, a great option is to Cash-Out Refi & use those proceeds to move on to your next project.

If it’s a flip, I could reason the cost.If the entire house is 103V, its an internally shorted main breaker (cheap), an issue on the power companies end (free), or a shorted common from the weather-head to the main (not rewiring the whole house).

For the phone number, there is no easy way it's usually hard to find except if you see a rental number on the building itself, ask the people in the building, of look in the common area for a phone number.Hope it helps!

Keep in mind that major problems are not common, so you may not have any expenses in a given year, but you still need reserves in case it happens. 

Its a pretty common planning tool.
