That's right, my friend. That was also a consideration for me when deciding whether to build my own house or buy a ready-made one. I was worried that the quality of the finished house might not be as strong as it looked. The materials used might not be the best. This made me hesitate at the time, and I decided to build my own house from scratch. Honestly, I initially calculated that I would have enough money to get it to the finish line. But now that the house is only 80% complete, I'm feeling doubtful. It turns out that the most expensive part is just beginning: the finishing, which will take more time and money. While I have no doubts about the strength of the house I'm building, I still don't know how much more effort and thought it takes to build a house. Sometimes I start to feel tired and impatient. So sometimes I think that buying a ready-made house wouldn't be as stressful. But I'm still grateful and trying to enjoy the process. 
The amount that will be spent on finishing alone might be higher than what you have spent on raising the structure. But you don't have to give up. Just keep putting in what you can afford, and gradually you will complete it. When you build your house, it's to your taste and style, so you have an advantage. Quote
That would be better. Building a house isn't as easy as it seems at first. And it requires patience. The stress isn't just about the cost, but also about the workers we hire who don't perform as expected. So sometimes I have to supervise to ensure everything always goes according to plan.
This is one of the reasons why I am not considering building from scratch. If you don't have time to supervise the workers, they will be irresponsible, cheat you and even steal some building materials. In my location, workers are so fraudulent that you need to be in the building site to checkmate them.
