Single family homes in these areas are few in number and wildly expensive, making more affordable multi-units hip places to live. The suburbs are full of newer single family homes that easily attract quality tenants. For the landlady newer homes mean less maintenance headaches and good tenants mean less time managing problems. Plus, instead of having two tenants and twice the management for a duplex, an investor can buy a single family home for approximately the same price in most areas of the country. If an investor buys a nice property, half the battle is already won.
Nice properties attract nice tenants.
Still, bad tenants like the better places as well. As a first step, landladies should always run a credit check on any potential tenants. Second, the landlady should go through her lease with her new tenants clause by clause. Third, every now and now a bad tenant will slip through. The best protection at this stage is to have All Risk Landlord's Insurance.
