What We Do
Full-service oversight, three ways.
01
Residential
Leasing, rent collection, and day-to-day operations for single homes, condos, and multi-unit buildings.
02
Commercial
Tenant relations, lease administration, and facilities oversight for office, retail, and mixed-use space.
03
Maintenance & Ops
Vetted vendors, scheduled inspections, and a maintenance line that actually gets answered.
Services
Everything a property needs, in one place.
01
Leasing & Tenant Placement
Marketing, showings, screening, and lease execution — filling vacancies with tenants who stay.
02
Rent Collection & Accounting
On-time collection, owner disbursements, and monthly statements that reconcile without a follow-up call.
03
Maintenance Coordination
A single intake line for repair requests, routed to vetted vendors and tracked through to close-out.
04
Inspections & Compliance
Routine walkthroughs and documentation that keep properties aligned with local code and lease terms.
05
Financial Reporting
Clear, owner-facing statements available anytime through the client portal — no waiting on email.
06
Vendor Management
A vetted network of contractors, held to response-time and pricing standards we set and monitor.
About Keystone Property Group
Run like the asset it is.
Keystone Property Group was built on a simple idea: owners shouldn't have to choose between hands-on care and professional systems. We bring both—a responsive, local team backed by clear processes for leasing, maintenance, and accounting.
We manage every property the way we'd want our own managed: promptly, transparently, and with a paper trail for every decision. Owners get real automation. Tenants get a team that answers the phone.
Transparency
Owners see exactly what's happening with their property — financials, maintenance, and leasing — in real time.
Responsiveness
Maintenance requests get a real response, not an auto-reply. Tenants and owners both get a person on the line.
Accountability
Every vendor, lease, and dollar is tracked and documented — nothing runs on memory or good faith alone.

To make alerts real: connect this portal to an email service (e.g. SendGrid) or SMS service (e.g. Twilio) through a backend, or a workflow tool like Zapier watching for new requests. Happy to help wire that up once you have an account with one of those.

Generate Property Owner Tax Document
Gross Rental Income, Maintenance & Repairs, and Management Fees are calculated automatically from existing records for units in the selected building. Every other field below isn't tracked elsewhere yet, so enter it manually before generating. Note: billing records aren't tagged by year, so Monthly figures match the selected month across all recorded years, and Annual figures include all recorded billing history — Maintenance figures are year-accurate since tickets carry real dates.
