I plan to build versus buy because Im currently working for my father, who is a general contractor in Fl, and will save on the construction costs because I can do most of the work for little cost other than materials. it would be minimum labor cost and no profit cost from contractor.

I feel you need to get by the work you have put in plus your value added material and expertise.

Composite materials are another option; they’re durable and low-maintenance, but they cost more initially.

One began selling custom flip flops, (bought their own material with money saved), Another who was always encouraged with a camera, attempted to take pics for young people proms, birthdays etc.Then they helped me with a former biz of cleaning up HUD properties during the housing crisis on early 2000’s.Next, but not all of the details for sake of my response.

We used the insurance company's preferred vendor for the smoke remediation… but we ‘made out like bandits’ on the painting / fixture replacement because they were wrote up  like $8,000 for the work and it probably took us 20 hours of work and $750 in materials to put things back together.  

Rising labor and material costs2.

No marketing material contained an ARV or Repair Cost.

Typically there is a metal plate between concrete and raw wood to avoid the rot.

Not furnishings but selecting the materials that will go into the new design of the home. 

Even without disclosing past successes, a sponsor would need to be disclosing present issues.What you're referencing is when trying to predict future performance is meant to mitigate the risk that a sponsors track record is considered marketing material.
