The 5 homes as a beginner is great however as you expand those quickly run out, and as far as I know the only way to get more homes is to donate. I think their should be ways to get more homes, for example adding them to the pointshop, or giving specific ranks more homes (prestige1, prestige 2, etc)
I wouldn't be opposed to this. I'm an Ult, so, I get unlimited homes, but, I know as a player, 5 is not many at all. If this addition was added to the prestige ranks, it would bump the number of homes up to 9, I believe, at the end of the ranking system. This is a modest addition to the number of homes, and would help players out, and encourage ranking up. The argument against this would state that the server needs money and buying homes helps fund it, but, let's be real, how many people have bought a rank purely to get more homes?
