I want to send a letter out to these owners and I'd like some help.

Great he then proceeds with telling me who and where to send a letter of intend to buy, i put an offer based on recent sales of similar homes within that area this was about 10 business days ago which i know they received it cause the bank person called me July 31 as i had left him a message the day before to be on the lookout for the letter.

If they are dissatisfied with a letter to the condominium corporation should I suggest that they contact the police and see what they make of it?

If you type the @ symbol, then type a space and the person's first two letters a drop down will appear for you to select.  

I've cam up with a $280k ARV because to properties on the street and block sold 7 months ago for just of $300K same style, rooms and similar sqft, only major difference is the house I might be possibly rehabbing has only 1 bathroom and the rest that sold for just over 300k has 2 bathrooms.

Do you have a yellow letter/mailer you're willing to share?  

In accordance with the laws of your jurisdiction, I would have him served with a No Trespassing letter now to prevent any future unfriendly visits.  

On this particular block there are no gas lines to any of the houses.

I used to get so flustered when I'd hit a road block and now I just nod when something happens. 

I've sent out 1 yellow letter campaign.
