A free lease toolkit, nothing to sign up for.
LoomLease answers the lease questions people otherwise work out by hand: what’s owed for a partial month, what a deal returns, what a notice should say.
Who it’s for
Self-managing landlords with a few units, renters sorting out a move, and small investors checking a deal. Property managers and leasing agents use the same tools for quick lookups.
How the tools work
Every calculator shows its working: the formula with your own numbers in it, and the common alternatives side by side, so you can see where a landlord’s or a seller’s figure comes from. Your inputs stay in the page address, so a copied link opens on the same result.
- Prorated rent calculator. Rent for a partial month, moving in or out, worked out three ways.
- Cap rate calculator. NOI divided by price, or the most you can pay for the cap rate you want.
- NOI calculator. Net operating income from rent, vacancy and itemized expenses.
- Rent-to-income calculator. Can you afford it, and does it pass the 3× rule?
- Rent increase calculator. Percent to dollars and back, the cost per year, and when it can start.
- Late fee calculator. Flat, percent of rent or per day, counted after the grace days.
The letters
Each letter fills in beside a short form as you type, checks your dates against your state’s notice period where one applies, and prints on one page or copies as plain text. They are templates: plain, dated and polite, and they point to the lease rather than make threats.
- Notice to vacate. Tenant or landlord, 30 or 60 days, dated and ready to print.
- Late rent notice. What’s owed, the late fee and the pay-by date in one letter.
- Rent increase notice. The new rent, the start date and the notice period, in writing.
- Rent receipt. A dated receipt for rent paid by cash, check or transfer.
Where the state rules come from
The state pages cover security deposits, notice to vacate, late fees, rent increases, landlord entry and small claims for all 50 states and DC. Each rule is checked against the statute itself or, where a page says “From an official summary”, a state agency, court or legal-aid guide. Every rule links to the section it comes from and shows the date it was last reviewed. Where we found no statewide rule, the page says so rather than guess.
What it isn’t
LoomLease is not a law firm, and nothing here is legal advice. The tools do the arithmetic; your lease and the law where the property is decide what applies. When a deadline or a deposit is at stake, check with a local attorney or a tenant or landlord association.
