Unless otherwise noted, we will not hold a property for longer than two weeks. This is subject to change during the off season or special circumstances.


All adults 18 years of age or older who will reside at the property must complete, sign, and pay for a separate application.


We do not accept co-signers to fulfill any rental qualification requirement.


All Applicants must provide a valid government-issued photo identification. All Applicants must also provide a valid Social Security Number, Alien Number, or I-94 for verification purposes. Non-U.S. Citizens must be able to provide documentation from U.S. Immigration to verify legal residency in the United States as of the effective date of the lease agreement.


A credit score of 650 is required of each applicant. 

We do not approve applicants with 30+ day late pays in the last 12 months, unpaid landlord debt, or unpaid utility bills. Credit is reviewed in detail, including collection accounts, late payments, charge off accounts, and past due accounts. Applicants that meet our minimum credit score requirement of 650 but have less than ideal credit may be required to pay 1.5 – 2 month’s security deposit.

Please note that we do not use a traditional FICO credit score. We utilize Resident Score, which is provided through TransUnion. We have a scorecard model that we use that evaluates an applicant’s credit history.There are several different factors that go into the CreditRetriever score along with the bureau score, including Income to Rent, # of inquiries, average age of tradelines, % of revenue to debt, percentage of bank tradelines to total tradelines, percentage of tradelines never delinquent of total tradelines, months since most recent delinquency and number of major derogatory ratings. Similar to FICO or Vantage, the CreditRetriever score is in a range of 350 to 850. While the new CreditRetriever score will not completely align with the more common FICO or Vantage score, there will naturally be some correlation.


We do not approve applicants with any open bankruptcies. Bankruptcies must be discharged for at least 2 years.


Applicant must provide the residence history for their previous two residences. Applicant must have verifiable rental history from an apartment community or property management company, or verifiable mortgage history for the last two years, paying an amount equal to at least 75% of the rent of the property they are applying for.

In the event the applicant does not have verifiable rental or mortgage history, but all other criteria is met (reviewed on a case by case basis), the applicant will be required to pay a security deposit equal to two month’s of rent.

When conducting the landlord/mortgage reference check, if any of the following are found, the applicant will be denied:

-Any eviction judgement, filings, or notice given by Landlord in the past 7 years
-Any unpaid/outstanding landlord debt
-2 more more late pays or NSF payments in the last 12 months
-Foreclosure on mortgage in the last 3 years
-Any negative reference from landlord in terms of violations, care of property, or poor condition left at move out.


All applicants must provide their last 2 FULL months of pay stubs or proof of income. Gross monthly income (before taxes) must be equal to or more than 3 times the amount of the monthly rent. All sources of income must be verifiable.


Applicants will be asked to disclose prior criminal convictions, or pending criminal actions. A thorough criminal background check will be conducted. Failure to disclose is grounds for denial. Convictions of any sort will be evaluated on an individual basis. Keyrenter will consider the nature of the crime and the severity of the crime, along with the conviction date. We do not rent to sex offenders. Applicants with convictions in the past 5 years relating to crimes involving violence, gang activity, arson, or injury to persons will most likely be denied. Applicants who have been recently released from prison, parole, or probation may be required to provide additional information and/or references.


Smoking is considered to be the use of cigarettes, vaping, e-cigarettes, and other forms of smoking. Keyrenter does not allow smoking in or on the property, or within 25 feet of any entrance of the property or a neighboring property. Keyrenter reserves the right to not process applications and rent to applicants who smoke. Any exceptions to this are on a case by case basis and may require a higher deposit.
