Your Partners in Profitability

Mainlander Property Management, Inc. is one of only twenty property management firms in the United States who have earned the prestigious designation of Certified Residential Management Company (CRMC). The National Association of Residential Property Managers awarded this title after conducting a rigorous on-site audit of our management systems. Criterion examined included compliance with all local, state and federal regulations, as well as compulsory operation procedures enforced by our staff of experienced managers.

Mainlander finds the right tenant in a timely fashion by marketing your property effectively. We showcase your property in our newly redesigned website.  We dispatch information releases to over 3,600 relocation and real estate specialists. Our website receives over 12,000 "hits" per month. Our leasing agents are available six days a week to show your property. 

Our Services

Property Evaluation

Our staff is fully qualified in property values, local neighborhoods and rental markets to advise you on appropriate rental fees for your property. We are thoroughly trained in the inspection of every kind of investment property, from single family homes to condominiums.

Tenant Screening

We take a professional pride in finding qualified and quality tenants for your property. In the past few years we've averaged over 500 home rentals a year with an average vacancy of less that two weeks.

Legal Matters

A selection of appropriate standard or custom agreement forms provide legal protection for both you and your property.

Rent Collection & Dispersal

Rents are collected by the fifth day of each month. Rental proceeds and late fees are paid on a predetermined date. In the event of late payments, collection practices are started promptly and evictions, should they be necessary, are handled in a timely and efficient manner to reduce the chance of difficult or costly situations.

Record Keeping

Each month you will receive a detailed income and expense report. At the end of the year you are provided with a comprehensive statement for your tax records. You always know exactly where you stand regarding income and expenses.

Our extensive list of reliable, reasonable and responsible contractors can cover any repairs or maintenance your property may require. Should an emergency arise we provide 24 hour care.
