Here are a few lessons I learned during the renovation, many of which stemmed from the age of the house and unexpected hidden damages:1.Damaged Plumbing: Several plumbing pipes were ruptured or severely damaged, requiring replacement.2.Termite Infestation: I discovered termites, which led to additional costs for treatment and repairs.3.Rotted Wood: Significant sections of wood in the structure were rotted and had to be replaced.4.Lack of Insulation: There was no insulation in the att Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I would find someone that can demonstrate that the pipes were properly insulated etc. did they say why they wouldn’t cover the chair?

During the renovation, I faced several challenges due to the home’s age and hidden damages, including ruptured plumbing, termite infestation, rotted wood, and lack of insulation.

After assessor comes out and consults with insurance company, they'll send demo guys out to come do demo work and remove wet drywall, insulation, etc. they'll usually put down dehumidifiers and let the place air out a bit to see what actually needs replacing and what was able to dry out.

Energy Efficiency ImprovementsInstalling energy-efficient windows, doors, insulation, and HVAC systems can appeal to modern buyers who want to reduce utility bills.

I ended up spending some extra time making the finished basement legal (add insulation and egress).   

Doors, windows, and insulation installed. 

You ever pay extra to insulate your house better so you can save on heating costs or anything?

I currently live in Southern Maine and am looking to construct some kind of new project rather getting into rehabbing existing residentialProposed Land Budget 100-200kConstruction Budget: 400kAll in 500-600k.I have found that if I do the site work myself including clearing, septic and digging the foundation is that i can sub contract out either steel or a Lester style building (50x150) for around 300k installed with insulation and power , divided into three 2500 square foot units. 

You might find that installing a mini-split system, properly insulating, and ensuring the finishes match the main home’s quality will make a difference in how the appraiser views it.
