I rent a 1900 sq ft home in 4s. Current sale prices in the sub are 525k.
In regards to the ratio mentioned above (150, 125, 100 etc), we are at 210.
Most in 4s are at least this or higher.
Luckily Im a proactive renter in the community (cleaning it up, alerting the landlord of community problems or happenings) so our rent changed by 0%. I know of a rental coming up in our community if anyone is interested and its the biggest model.
