Know Your Numbers Before You Buy, Rent, or Evict
Free calculators for Charlotte landlords and investors. Use them on our site, in Claude or ChatGPT, or in your browser. No account, and we do not store your numbers.
THE TOOLS
Which Decision Are You Facing?
Each calculator answers one question with your own numbers. Pick the one that matches where you are.
For homeowners and landlords
Should you sell it or rent it out?
Two paths, and one is hard to undo.
Compare selling today with renting for a set number of years, including federal and North Carolina tax.
A tenant stopped paying. What will it cost?
Every week you wait is another week of unpaid rent.
Court costs, lost rent, turnover and your time, plus what 30 more days adds.
For buyers and investors
Will this rental cash flow?
A house can look right and still lose money every month.
Monthly cash flow, cap rate, cash-on-cash return and debt coverage from a price and a rent.
Analyze a listing as you browse
The county record tells you what a property is, not what it earns.
The Landlord Analyzer, a free Chrome extension, pulls the Mecklenburg County record, estimates the tax and shows the rent a deal needs.

FAQ
Landlord & Investor Tools Questions Answered
What free tools does QCMS offer?
Three calculators: Rent vs. Sell, Eviction Cost, and Rental Cash Flow. There is also a free Chrome extension, the Landlord Analyzer, for Mecklenburg County properties, plus Claude connectors and a ChatGPT app that run the calculators inside a chat.
Do I need an account?
No. None of the QCMS tools asks you to create an account or sign in.
Do the tools store my numbers?
The Claude connectors and the Landlord Analyzer do not store them. Each has a privacy page that says exactly what is kept. The calculators on this site use the numbers you type to show your result.
Do they work outside Charlotte?
The calculators work with any numbers, but the defaults and the legal and tax notes are for North Carolina. The Rent vs. Sell Calculator models North Carolina state income tax only. The Landlord Analyzer works only for properties in Mecklenburg County.
Which one should I start with?
Start with the decision in front of you. Deciding whether to keep or sell a house you own: Rent vs. Sell. A tenant has stopped paying: Eviction Cost. Thinking about buying a rental: Rental Cash Flow.
