Here’s what to consider based on your situation as a first-time landlord:Tenant Backs Out After Signing a LeaseSince your tenant signed a 13-month lease and paid a deposit, the lease is legally enforceable unless it includes a cancellation or early termination clause.If no such clause exists, the tenant may still be liable for rent until you secure a new tenant.The agency can generally retain the deposit to cover unpaid rent or costs related to re-listing.Any resulting legal fees or rent loss may be deductible on your Schedule E when you file taxes, as part of rental-related expenses.Appealing Your Property Tax AssessmentIf your property taxes increased significantly, you can file an appeal with your local assessor.A successful appeal, supported by comparable property sales or valuation errors—can reduce your property tax bill, improving cash flow.While insurance premiums are not directly tied to tax assessments, a lower assessed value may affect premiums if your policy is based on replacement cost or uses assessed value as part of the underwriting model.Should You Put the Property in an LLC?
