I have a former client who wanted to save money. He gets what he pays for. They don't have local representation and rely entirely on VAs to coordinate repairs/showings. The client ends up paying me more money for repairs with hemlane, than he did for both management fees and repair costs through a local pm.
Don't be a cheapskate, hire a local, knowledgeable property manager between 250 and 750 units, and rest easy.
