@Alex BalanLook for rentals listed in the area you're considering, then find comparable rentals in comparable quality neighborhoods of other locations, preferably locations you're familiar with.  

I advertised it stating high speed internet was available but never claimed low speed internet was available.

Best advice i can give you is to get active on the website ask and answer questions that you know and the speed at which you will learn will be shocking. 

That way, you spend as little as possible to quality check your list.But if you're pretty sure about the addresses, then an envelope is OK.And keep it simple, no long paragraphs!

Hey Lou,Cost, time a quality will be the key to anything you will take on.

I have a cheap option for granite and a more expensive option that was definitely better quality work

Give the seller the highest standard of quality services and protect yourself from dishonest people but overall be honorable.

@Kevin StoneWhat quality of property are you looking for?

Does anyone have a suggestion for a high quality, simple sales contract?

Your question is a very important one, as finding great deals is way more than half the battle for successful real estate investment, IMO.At their core, most strategies seem to be to focus your acquisition targets and process to either eliminate as much competition as possible while still acquiring quality properties and/or by developing and leveraging a competitive advantage.
