It's not really possible to distinguish how much, if any, more money is being paid for houses with a PV system.

I know a lot try to undercut on the big three terms but what kind of service would distinguish them?

A little late to the party, but same advice as above...In my experience, all homes have some sort of mold, and mold testing companies will find it -- so there is that portion of it.I think it is important to distinguish that you want a mold testing company that ONLY tests for mold, NOT a mold remediation company that is highly interested in remediating that mold.

I went through the same coverage explanation with the attorney who refused to accept my reasoning and kept citing inapplicable cases which I distinguished from this situation. 

It may be too late, but I would use the next one as an opportunity to distinguish yourself from the competition.

Attention to detail is the only distinguishable characteristic one generally needs to do the job, their is no degree behind it or general skill that takes one years to learn to limit the labor force to allow them to price gauge.Same thing for lawn maintenance, I call the big companies and they quote me 40 bucks per mow, I call a handyman and he quotes me 20bucks per mow... mowing is mowing folks, there is no degree or distinguishable reason to mark up the price beyond what it is.

There are decent higher-end laminate options that are tough to distinguish from hardwood.  

The guy from the county office said each property listed is at least 1 year delinquent on the taxes but he is unable to specifically distinguish how many months or years each property is delinquent.

One needs to distinguish between gross cash flow, and net cash flow, and then also between Return on Investment and Return on AssetGross Cash flow is your rental, net Cash flow = :Rental - Expenses - Tax.Where you put down 25% of the value of the house, you finance 75%, and the interest on that 75% is tax deductible.

Most times, it's being able to distinguish yourself by using a certain color and using handwritten ones.
