Look into the ad budgets of companies like Procter and Gamble, Car Manufactures, Cell Phone Companies, or Insurance Agencies.

Real estate is gambling.

The concept is simple ..you step in the car .. turn on the ignition and you put it in drive.

A fire ignited at the warehouse, killing 36 people.

I haven't purchased this way before, and unless you can gamble a bit of cash without having a contract, I wouldn't suggest it.

They may want to gamble on someone else not knowing the 20 year old HVAC, but as you mentioned, it's going to come up during the inspection.  

Fortunately, the calculated gamble had paid off.

I don't see huge upsides as there is only a few years left in the up swing and after transaction costs, it's not that fruitful to buy now and hold for another 5 years or so.Also, I'm in earthquake country and insurance is a gamble at best as they may deny a claim.

Being a middleman- Realtor, contractor, ect -and get paid off the "investors" gambling. 

If they found the likely ignition source, it will say it in the report.
