If the lot is 20k and the lot can be zoned for a modular home which would cost $X and should sell or rent for $X that can help buyers feel comfortable with the deal.Having contacts in the area like realtor, architects, and builders can help assess the zoning, structure, and cost for construction (also can be referred to the buyer if they are seeing this as a "package" deal).

One of the properties is leased back to the builder so I never have to worry about that.

We will be the builder.  

New build costs vary depending on who your builder is obviously and the costs of materials.

That includes builders and rehabbers as well as John and Jane Q.

My heart was pounding and my whole body was shaking. 

Is there anyone out there that can recommend a good boat builder.

Hello I’m looking for recommendations for a cpa/bookkeeper that specializes or deals a lot with home builders, developers, and other real estate investments.

Too many weak properties, your body isn't holding out, minimal support in a pinch from your wife or other handymen you know?

Builders?
