Automation That Works For You
Syncs with QuickBooks to continuously identify tax savings as improvements happen — no manual tracking, no missed write-offs.
Most real estate owners lose money without realizing it. Here's where it's probably happening to you.

You're probably missing tax deductions worth $50K-$300K+ per property. Most investors only claim them once — if at all.

Premiums go up every year while gaps in coverage put you at risk. Most landlords overpay and don't even know it.

Without the right legal setup, one bad tenant or accident could take your home, savings, and everything you've built.
We apply modern fintech and AI to the biggest financial blind spots in real estate — taxes, insurance, and ownership structure.

Common questions about tax savings, insurance optimization, and asset protection for rental property investors
Overline is a financial optimization platform for rental property investors. We help you maximize tax deductions, reduce insurance costs, and protect your personal assets through proper legal structuring — all in one place. Instead of piecing together CPAs, insurance brokers, and attorneys, Overline applies modern fintech and AI to handle the biggest financial blind spots in real estate automatically.
Most investors only claim depreciation when they buy a property. We find deductions upfront through cost segregation, plus ongoing savings every time you renovate, replace appliances, or improve the property. Our platform connects to QuickBooks to automatically identify deductible expenses you might overlook — turning your bookkeeping into a tax-saving engine.
Cost segregation is an IRS-approved strategy that accelerates depreciation by reclassifying parts of your property (flooring, fixtures, landscaping, etc.) into shorter depreciation schedules — 5, 7, or 15 years instead of 27.5 years. This front-loads your tax deductions, often generating $15,000–$50,000+ in year-one savings on a typical rental. Overline estimates your potential benefit for free, so you know if it's worth it before paying for a full study. See <a href='/blog/how-much-does-cost-segregation-save' style='color: #004643; font-weight: 600;'>actual savings by property type</a> or use our <a href='/blog/is-cost-segregation-worth-it' style='color: #004643; font-weight: 600;'>decision framework</a> to evaluate your ROI.
Insurance premiums creep up every year while coverage gaps put you at risk. Overline benchmarks your rates against our carrier network to catch overcharges, and we use your cost segregation asset inventory to document property values — which speeds up claims and helps maximize payouts if something goes wrong. Your tax analysis doubles as insurance protection.
Without proper legal structure, one tenant lawsuit could threaten your home, savings, and personal assets. An LLC creates a liability shield — if something happens at your rental property, creditors can only pursue the LLC's assets, not your personal wealth. Overline helps you set up LLCs and trusts the right way, keeping each property's risk separate from you and from each other.
Your CPA files your taxes based on what you give them. Overline proactively finds savings they might miss — like ongoing depreciation from renovations, insurance optimizations, and partial asset dispositions. We don't replace your CPA; we make their job easier by surfacing opportunities and providing documentation they can use directly. Think of us as your always-on financial co-pilot.
Overline is designed for working professionals (W-2 employees, business owners, high-earners) who invest in rental properties on the side. Whether it's your first rental or your tenth, we bring institutional-grade financial optimization to individual investors — the same strategies private equity and family offices use, but accessible and automated.
Start by joining our waitlist — we'll invite you to connect your properties and run a free analysis to show your potential savings.
