Home Inspection questions, answered by experts

In many cases, you can sell your house if it has aluminum wiring, but you are likely required to disclose that fact during the sale. In some cases, your city or area may have banned the sale of homes with aluminum wiring, so you’ll need to update the wiring or arrange for its replacement as part of the sale. In some cases, it will benefit your home sale to replace the wiring system before putting it on the market.

Sometimes, issues with the HVAC system or an unbalanced washing machine could be the reason your house feels like it’s moving, but it could also be other factors. If a large truck passes your house or there is construction in the area, your house may feel like it’s moving, but it will be short-lived and not a sign of a larger issue.

A dryer vent inspection is simply the process of checking the vent for the possibility of damage or clogs. You can do it yourself or hire a pro. Pull the dryer away from the wall and inspect the portion of the vent that’s behind the appliance for lint buildup or kinks. Check the connection of the vent to the wall for loose parts or lint that’s escaping the vent. Check the exterior exhaust vent for signs of damage or lint blockage. A pro can check the length of the vent inside the wall for you. 

From the underwriter to the home inspector, the team working to help you buy a house is there to make sure it is a sound financial decision and that the house is worth what you're paying for it. 

A sale can fall through when a mortgage lender discovers the cost of the home plus closing costs is too high for your current financial status. Another potential issue is that an inspector or appraiser can find issues with the home that halt the sale if the offer is far higher than what it's worth.

The age of the well, installation methods, and maintenance logs can affect your home insurance premiums and any potential future claim. Mortgage companies can request proof of water quality before they approve the loan. Review all well information, including the Shared Well Agreement, before you make an offer to purchase.
