Vacant Property spotted, Owner(s) found, Now what?

[John Sherron]

Okay, I think I found a great potential property and I did the research and established the owners. The home looks to be vacant, the grass hasn't been cut for weeks and it looks to be about 2 feet high at this point. It looks empty but not certain about that.

My question is should be the next step? 

Before reaching out to them, should I have a figure already put together on the property and give it to them in the first letter or just contact them about my intentions?

Without knowing what the inside of the home looks like how do I come up with a realistic offer?

Any advice or other input that is essential to know in this process please advise if any. 

Thanks so much in advance BP Family! Look forward to your responses.
