## Where it usually goes wrong

1

### The special is spread over a 12 to 24-month term

Eight weeks free sounds like two months of rent. Spread over a 15 or 18-month lease, it lowers your monthly number less than you think.

2

### Required fees sit outside the base rent

At 12 board buildings, required fees ran $43 to $226.88 a month, median $141.50 (fee survey, Oct 25, 2026). The ad shows none of them.

3

### Renewals price from base, not the special

When the special ends, your renewal starts from base rent. At the board median special, year two jumped about 20% on Oct 25, 2026.

**So we price every building after the special, the fees and year two, and we confirm it in writing.**

## About the tools

### Are these calculators accurate?

They use the same formulas we publish on our method page. They are estimates; the community sets the price and the special.

### What do the defaults show?

Our calibration examples: 8 weeks free on a $1,500 base with $141.50 in fees, a DNT commute from Frisco to downtown, and 6 weeks on $1,350 vs 8 weeks on $1,500 over 24 months.

### Do you store what I type?

No. The calculators run in your browser and nothing is sent to us unless you submit the shortlist form.

### Can you guarantee a price or approval?

No. The community sets both, and we confirm them before you sign.
