If it's beyond normal, do I just charge what it costs to fix it or do I have to discount the cost for "normal wear and tear"?

I'm building a 3-flat in East Garfield Park, west side neighborhood of Chicago.  

You’re financially protected more with more units/doors.Of course more income.Cons of larger multi family are barriers of entry costs to acquire, operate, and experience.

Rehab starts in my third property in 3 days.So I am a fan of The Flip Secret. but I recognize the cost is significant, and everything you learn can be found in other places.

Having to add it later would prove even more costly. 

I would also have a good appraiser to an ARV apprasial so you know the numbers all work  IE land costs and build cost and then there is significant equity still there. 

IMHO I think the draw to the Poconos is it's proximity to two monster metropolitan markets and their middle and professional class who may prefer in many cases to tone it down from places like Miami, Hawaii, Vail, or Stowe, and instead have the luxury of a 1.5-2 hour car trip to somewhere where they will save on airfare, get a good deal on their accommodations, and still have loads of fun with their families without having to deal with exorbitant vacation costs and aggravating travel arrangements. 

That could (Could doesn't mean does) mean mom is showing on title to Wells so, she would have (could) reason to pay the loan off to avoid losing it in foreclosure, if that is a viable option.It would not appear any solution is without cost.

Quote from @Richard Hoyte: What is a good and or acceptable amount of money to have saved up before buying your first rental property I'm aware this can vary depending on the state/area but is there a rule of thumbThank you ahead of time  Hello Richard, Your down payment amount will have a lot to do with this.If you are going with the minimum downpayment of 3 - 3.5% , you'll want to have at least a total of 10% of the purchase price (to also account for closing costs) + 6 months in reserves.

If there is any value, it would simply reduce the cost.
