From landlords, for landlords
Take back control of your rentals.
We're a small consultancy team with our own rental portfolio. We built our own AI system to run it, and now we build them for other landlords: tenants, repairs, certificates, paperwork and deals, made around how you work and owned by you.
1. Where are you now?
2. Tick what you'd like
Pick a stage above and we'll tick a sensible starting set. Change anything. Every piece is optional and made in your name.
3. Your starting point
Tell us where you are and we'll suggest where to start.
Tap a stage above, then add or remove anything you like. Nothing is set in stone, and the free call is where we work it out together.
Who we are
Landlords who built their own system
sift.house is a small consultancy team with our own rental portfolio. Nothing off the shelf ran it the way we wanted, so we built our own system. It worked, and now we're sharing it.
We've done it ourselves
Rent chasing, gas safety dates, repairs at midnight and deals that nearly added up. We built our system to take all of that off our own plate before we offered it to anyone else.
We build it with you
You don't need to be technical. We set everything up around how you already work, show you how it runs and keep it running. Start with one piece or have the lot.
You own it, start to finish
Your accounts, your data, your criteria. We never hold your logins, never sell your data and never take a finder's fee. Stop any time and take everything with you.

Three flats in Whitley Bay, an HMO in Leeds, six homes run from Riyadh, a block in North Shields and more. What each landlord needed, what we built and what it looks like.

What a system like yours looks like
Three pieces most landlords start with: a dashboard, tenant messages that send themselves, and paperwork in your own brand. All examples, all made-up names.
Build your own property dashboard
Every property, tenant, payment and deadline in one place, laid out the way you think about your portfolio.
- Rent due, received and late, at a glance
- Gas safety, EICR and EPC dates tracked for every home
- Rent reviews, mortgage fix end dates and empty periods flagged early
- A monthly summary email, so you never have to log in to stay on top
| Property | Price | Yield | Score |
|---|---|---|---|
| 2-bed flat, Stockton TS18 | £64,000 | 9.1% | 88 |
| 3-bed terrace, Darlington DL1 | £89,950 | 8.6% | 84 |
| 3-bed semi, Middlesbrough TS5 | £105,000 | 7.8% | 79 |
Four ways the same five homes could look. Made-up figures; yours is built the way you like to work.
Manage your tenants automatically
Friendly, timely messages go out on WhatsApp or email without you lifting a finger, and replies update your dashboard.
- Rent reminders before the due date, and a polite nudge if it's late
- Gas safety and inspection visits booked and confirmed
- Repair requests logged with photos, straight into your system
- Rent review notices drafted with the right notice period, so nothing is missed
