I think immigration is a big issue that could affect many industries but may have huge impact on construction and restaurants which I would bet to be two of biggest industries in this country (I don't have any facts to back up the restaurant industry claim).I've already felt the effect of the value of the american dollar dropping by many of my Polish Contractor's employees moving back to Europe and fewer new Polish immigrants coming to replace them.

The biggest plus in my opinion is you can receive commission on properties you buy for yourself (at least in Wisconsin).

That was the biggest expense.

A brokerage who deals in SDRPs invested in real property rather than in "markers" in The Wall Street Casino!

Maybe more attic insulation will give biggest bang for buck, or duct cleaning, or changing the filter more often.

Used the scraper to get the biggest spots.

Melissa Gittens for the financing the biggest hurdle was getting the 25% downpayment.

I don't know who has the biggest slice of the old S&Ls as most changed to State Banking Charters. 

@John Thedford surprisingly, one of the biggest lenders in NJ requires a pretty big upfront payment. 

Your biggest challenge might be to find a qualified and honest contractor who won't do their best to rip you off. or somehow delay your project because then busy expending resources on bigger and more profitable jobs this while already holding on to the initial payment you gave them.
