Listen, tbh people will pay a little more if it means not so much of a tacky house......I have found it out myself. and also, if you want to get yourself out there as a good, or even just a decent builder, you need to put a little bit more into it. For example, the first 3 months I built on meepcraft for people, I lost about 25k a build. Try to get your name out there first so it will be worth more later. After the first 3 months I built, all the other builds of mine gained at least 75k-100k.
Good luck!
