Just a fun little tidbit, but once you unlock the rental manor in town and do Victoria's panty quest you don't really need to worry about paying rent. Whenever she comes by after that, not paying rent results in sex with zero monetary cost. This basically lasts until you get her pregnant, at which point you just need to slay her bastard stepson and his thugs so you can become the mayor and get that house for free.I know I'm late in this game, but it has been a blast to play... after figuring out that resting one night doesn't fully restore health and magic points. And, it's a struggle to make enough money to pay for living expense.
Basically any of the girls you progress far enough with to impregnate earns you another free rest zone, and assuming you don't abandon Gwyneth after knocking her up the most you're going to pay is 25 gold (14 for the field, 6 for your Bat Breeder and 5 for the guards). Most of that will be covered by tax revenue, and if you're also churning out enough goblin offspring to do raids, you'll be making 20-30 gold a week.
