But one main easy reason is:They are not built for long term, they are not build to withstand harsh conditions of weather.

If your a greedy person let me know and I will take you off my list of people to have a shot at properties I have managed to get at a very good price so you won't have to worry about me making money you feel should be in your pocket.Sound harsh, well I don't want to deal with greedy people and have used that exact response about half a dozen times in my life and they continued to buy from me without any more BS.

They do not want the cold harsh winters anymore at their ages.

I dont mean to be harsh, just trying to be honest with you.

My intent is not to be harsh, but wholesaling is not the easy path the gurus make it out to be.

(Am I being too harsh?) 

They Know there is a vacancy and repairs part of this, they chose to not include it.am I being to harsh?

The option money may be non-refundable but the amount will or will not be credited back to you if you do close on the property.Another item you mention is disclosing a defect-Texas has implemented some very harsh wording that states the Seller has to disclose, and if by chance the Realtor is aware of the defect they need to make sure the Seller has disclosed-lets face it we are all scared of any legal action. 

Sorry Peter, this is going to be a little harsh.  

That's certainly your prerogative, but when you are cutting corners, don't be surprised when you attract customers who want to do the same.Sorry if this comes off as harsh, but I call 'em like I see 'em...and I hate to see people cutting corners in this industry.
