I have taken the initiative to get rid of unnecessary monthly payments such as cell phone plans, car payments, etc. 

AdvantagesTypically unreported on the borrowers credit profileFlexible loan termsPossibility of a wrap down the roadAble to acquire more the 10 property limit imposed by traditional underwriting guidelines Less stringent underwriting from the lender

I feel making an offer just to get it under contract and off the market is deceptive and causes a lot of unnecessary stress.

I’m not going to say it’s a mistake, but I feel it is completely unnecessary.

Are there any cons of a direct mail campaign besides the unnecessary costs?

Something you've chosen to endure can be far less unpleasant than something imposed upon you.

He actually called the seller and told him the ballpark our offer would be in and sent me a text stating that it was unnecessary to submit an offer as the seller didn't want us to waste our time.

@Chris Adams you're probably right that in your area it is different than in Georgia.With that said, in Atlanta the water company is also owned by the city and the law here states:(c) A public or private water supplier shall not impose a lien against real property to secure unpaid charges for water furnished unless the owner of such real property is the person who incurred the charges.

Also the fact that we beautify our area with unnecessary additions.

Also, any unpaid code violations fines might also be imposed to the new owner.
