Reached out to customer service and they're completely unapologetic.

Rental income finances everything in all of them including all the custom upgrades and upkeep done mostly by hired hands.

My wife and I are considering buying a plot of land and either building a custom build on it or putting a manufactured or modular home on it.

A new/improved road here will also benefit them as well if you are bringing more customers to their shopping center and providing more access points for traffic flow in/out. 

While this option may require permits for the renovation work, it may be a simpler process compared to replacing the entire home.Ultimately, the decision to replace or renovate the mobile home will depend on your budget, timeline, desired level of customization, and future resale value.

Be sure to employ pattern-interruption also.

Customer service is unwilling to refund anything on, essentially, a defective product. 

And if you become a repeat customer they may do the same for you. 

My main source of income is a full time W-2 job with a custom home building company (S-Corp).

On the refaces we just paint the face frames white and he comes in and measures and cuts out the cabinet doors out of melamine that has a slight off white wood pattern.
