The insight from this and my other threads is for now that I should place more trust in my "business partners."
A healthy distrust is absolutely appropriate in this industry—especially in boom times, when the level of botched work traditionally rises. But this should still not mean control mania, where you sit on the executor’s neck with constant oversight.
There are different sellers, different company philosophies.
Even big names with otherwise high quality levels and price appeal unfortunately rely on commission whores in sales, whereas the small general contractors (regardless of construction type)—usually competently owner-managed—the seller is also the boss in one person and addresses complaints preventively through communication.
A small prefabricated house general contractor from the region would be my preference, but despite weeks of research, I simply haven’t found anyone like that.
Take a targeted look around the new development areas and ask the builders. Look at the company signs on the cars. Not everyone has a homepage. Some rely on word of mouth.
The small timber builders don’t call themselves "prefabricated house manufacturers," but "carpenters" or similar, likewise the solid builders call themselves "construction companies." It’s unfortunately no guarantee, but almost a sure sign to recognize solid small general contractors: they don’t waste their energy on flashy websites. On the contrary: I myself have done well for decades in a completely different industry with the strategic decision to keep the general public away with a terribly hard-to-find website, customers I don’t want anyway. In referral business, the saying goes "the apple doesn’t fall far from the tree," meaning a satisfied customer doesn’t recommend a service provider to the biggest idiots they know, but to
good acquaintances. That means you don’t get an unpunctual, nitpicking pain in the neck as a new customer recommended by a friendly, reasonably communicating customer.
It has already come up, but always remember: you only build 1 house, but get (for example) 5 offers made. That means 4 "sellers" go empty-handed, and one wins the jackpot. From a seller’s perspective, that’s an average success rate of 20%. Unfortunately, this sometimes leads to sellers’ efforts being reduced to only 20% per customer.
If that were the case, that would be nice. Unfortunately, many prospective builders first get an overkill of offers before they (at least sometimes) get brought down from their dreams by forums like this, realizing they can’t set up a castle in the air on their plot at prices from just after the fall of the Berlin Wall. So first, 5:1 is by no means accurate (because for every 5:1 customer who signs with one of the five providers, there are still two 5:0 customers who only realize their daydreaming after the inquiry), and second, the remaining one often takes so much time that the salesperson has already left the company. Seen that way, one should be able to understand the sellers.
