It depends on what you’re renting and where exactly it is at.
Two checks are craigslist. For a four bedrooms, high 2000s look doable. There are only 14 listed, but only two are higher than your rent, one wants $12,000/month for their “executive” home and the other wants $5750 (can you say please pay my mortgage?).
If you’re in a four or five bedroom and it isn’t spectacular, you’re probably paying too much. If you’re in a 3 bedroom, you are paying too much. Probably $1500/month too much.
The second is rentometer.com. They come in high IMHO. They use advertised prices.
