Those  are appropriate only for widows and the elderly

As well as you know how to do different types of renovation projects such as "concrete to decks, to widows, siding, roofing...etc" this is versatility, compared to other contractors that only focus on one field, this could the investors benefit from.How would I build a clientele? 

You can call down the obituaries and work to convince the widow to sell their house under market, with the "value" you add being you'll help her move into an old folks home.

The contractor will open the widows i the winter to let paint fumes out but will turn up the heat all the way.

This opened a widow to change the zoning on this piece of property.Another challange I ran into was the access beside the existing house to what would become the access for two more houses in the rear of the property.

Despite her skill as a spy, Black Widow is troubled by her history.

As for not screwing the basement widows shut...hindsight is a wonderful thing.

I  live in Florida, and am widowed.

Then, doing again, and again, and again..The strategy is not much different than say, "marrying a rich widow..." 

I look up the owner to see if it's this guy (it's not - it's a widow) and get in contact with her and she tells me someone is going to buy it for 25K and she's waiting for him to secure financing.
