Alaa Kandil

Co-founder of Rentmark

Alaa Kandil is the co-founder of Rentmark, property management software for independent landlords who run their rentals themselves.

At Rentmark, Alaa builds the tools landlords use day to day: rent tracking and receipts, state-aware lease generation, move-in and move-out inspections, maintenance requests and rental accounting.

Every state-specific figure cited in these articles — security deposit caps and return deadlines — comes from a single table, and each one names the statute it comes from so you can check the source yourself.

Alaa is not a lawyer, and nothing on this blog is legal advice. Landlord-tenant law changes, and cities often add rules on top of their state's. When real money or an eviction is at stake, talk to a local attorney.
