Never stop improving!

Don't leave income on the table just because you will be taxed on it.3) Most real estate expenses are deductible in the year you pay them, especially if the benefit is immediate (like a utility payment or property tax).4) Some expenses are prorated through the life of the improvement, such as depreciable buildings and roof repairs.

Closing costs and holding costs will devour the rehabber's gross profit.And a rehabber is going to demand title insurance before sinking $50k in improvements into this thing.I recommend you move on to the next one!

In low/no appreciation markets, you want higher cash on cash returns that will offset the lack of appreciation and so you can at least exit the market in 7-10 years if you need to without losing money or you will have been able to save some of the cash flow to make capital improvements and continue to hold the property.Also, you want to buy at a discount so that much of the equity margin you need to avoid selling costs eating up all your aggregate cash flows is captured at purchase (and perhaps some significant gain above that).

Adding another bathroom will improve the property value.

That is much more likely to be considered a capital improvement, at least in part. 

The property card will tell you land value, improvement  value, how many years back taxes, etc.

How do you define "over improving?"

My question is other than Home Improvements Shows, which other ways of marketing are everyone else using that generate good leads?

Often next (or simultaneously) usually, but not always, some property improvements are in order.
