No off-street parking
Tenants strongly prefer a driveway or dedicated parking pad.

HOAs or municipalities that restrict rentals
Some HOAs limit leasing, and the Dellwood municipality (in parts of 63135 and 63136) also has restrictions on rental properties.

Homes or apartments backing to railroad tracks or bordering highways
Noise and vibration can limit rentability.

Small homes (under 700 sq ft) and one bedroom homes
They attract a smaller tenant pool and often have lower appraisal values.

Low ceiling heights (under 7 ft on upper levels)
Most municipalities in St. Louis require a minimum ceiling height of 7' as one of the qualifications for a bedroom.

Homes on double yellow line roads
Indicators of busy, high-traffic streets—less desirable for long-term renters.

Homes or apartments in flood zones, or with fire or flood damage
Flood insurance costs can be high and limit cash flow. Fire or flood damage often comes with hidden issues and insurance limitations.

Homes or apartments with significant foundation problems
Costly, unpredictable repairs and potential occupancy issues.

Homes bordering Coldwater Creek
The creek has a long history of nuclear-waste contamination concerns.

Septic or well systems
Higher maintenance; most investors stick to public water/sewer.
