I've read material through various resources that buyer pays closing costs as long as it's put in the agreement. 

Only material cost was link ties and new poles and a couple of bags of concrete, and labor was around $200-300.

I've consumed so many BP articles, podcasts, and other material.

I suppose the question I am asking is more in reference to marketing materials/implementation strategies specifically.

Have heard of Habitat Restore for cheap material and will definitely look into that.Any tips to installing these windows that I need to be aware of?

This is not to say you should use cheap materials.

I’m curious as well, I just had some marketing material returned as vacant property with no forwarding address at a property where the owner passed last month.
