as others have noted, the house stuff is wrong.

- compound interest should be the default.

- when asked rent and house expenses as a percentage, is it a percentage of initial cost? current value? future value? It doesn't really make sense as a percentage. I don't charge a tenant X% of my cost, I charge market rate which may be more, or less than my actual expenses.

- same for taxes. it's a nearly fixed amount that increases over time, but trying to do it as a % calculation of actual dollars is often incorrect because that's not how it's calculated in real life.

good points. sounds like there need to be some controls added where you choose how you'd like to specify those values.
