Did you use the Pro desk at home depot or just your own credit cards?

I went to ask questions about zoning on a property ( I didn't even know what I was talking about at that point) and the architect who was on line overheard and offered to help and provided his business card; right after he handed me the card, I watched him go into the office of the zoning officer for a private meeting, which was a good clue. 

I normally find the curious guy/gal and give them my card

First day... but if they're good tenants, I remember their birthdays, give Christmas cards, and certainly, have no issues asking them if they have thought of seeing their dr.

I used to own (until 12/2015) a large WU agency, so maybe I can help.On the sending end, you  could pay with a debit card. 

She had about 40-50K in Credit Card Debt. 180K owed on the MTG and house is worth about 230K as-is. 

That verifies their face matches the ID card and gives evidence they were on you property at a certain day/time.

Ask them if they know anyone and give them a couple of your cards to pass out to those that are consistently in buying roofing supplies.3) Tax laws in the states are so much different than in Canada, but I can't seem to think that there's a way you could write off an expense that you haven't purchased yet.

Go to sheriff sales and hand out your business card if you have one, create an online sign-up form and market it all over social media to get potential buyers to sign up...etc etc etc.......so many things you could be doing to attract buyers.

Those are generic and dozens of people mail them they same crappy post cards and letters over and over again.Your market is different.
