sorry trying to figure out how to reply to this.
I'll go with my personal view. I would rather stretch any payment for a snake over a couple of weeks for a few reasons.
1.) When trying to maintain my lack of debt, it's important to establish a good buffer of income incase of emergency expenses, and savings just because I have the option to drop a good percentage of my paycheck on a snake does not mean I want to, and honestly if that person(s) is maintaining their life well, there's no reason that a snake isn't a good investment of their money.
(basically I doubt snakes are causing the 100$K debt per house).
2.) If you're new to the scene, like I am it allows you to establish a good relationship with your seller, something that I believe to be priceless regardless of what you're buying (for instance I was able to call the guy I bought my car from and ask him some questions after he had no obligation to help me and he was nice enough to answer because we had established a buyer/seller relationship)
sorry, that might be a little long winded.
