Remember, if a deal is truly off market, you have an owner who knows they are able to sell and is choosing not to take the very simple step of listing it.  

This method is simple but not precise.

I believe that you don't get returns (failed to deliver) with bulk mailers so you don't know which addresses are bad.That's the simple stuff.My advice is to do various mailings that you or some prepares locally, that go out immediately, using 1st class postage.

But it might be a good idea to raise rates each year or so by $50 to $100 because it can communicate that you aren't completely checked out, and you value your property, your time, your investment.

You can always start with the Simple Start subscription and upgrade if you find that it isn’t meeting your needs.  

We have been customers for more than five years, we would appreciate having better communication when it comes to the property managers having Important issues to solve.Therefore, please contact me at any time at 703-420-0620 or 703-317-7078.

Simple math, right?

It's just that simple. 

But, people tell on themselves when answering simple, straightforward questions.

Be responsive, communicative, deliver on what you say you are going to deliver (e.g. photos are true representation of your properties, amenities reflect what you actually have).
