HOA dues are $1100/mo but expecting them to increase to about $1500/mo by the end of the year. 

I do believe cost is a factor.

Late fee is considered reasonable if it is not more than 12% of the rent for the rental period under the lease for a dwelling located in a structure that contains not more than four dwelling units or 10% of the amount of rent for the rental period under the lease for a dwelling located in a structure that contains more than four dwelling units or the late fee is more than the applicable amount but not more than uncertain damages to the landlord related to the late payment of rent, including direct or indirect expenses, direct or indirect costs, or overhead associated with the collection of late payment.A late fee may include an initial fee and a daily fee for each day any portion of the tenant's rent continues to remain unpaid, and the combined fees are considered a single late fee.

Improving the house can Increase your cash flow a little. 

Breaking the lease without the legal justification may subject the tenant to payment of the remaining rental fees, damages and cleaning fee and other costs indicated in the lease agreement.
