See the numbers before you see the house.
Every deal starts with the same questions: what will it cost to buy, what will it earn, and what is the area really doing. We build investors and sourcers tools that answer them on one screen from official data, then turn a good deal into a clear pack for your investors.
Good deals are found by people. The admin slows them down.
Investors and sourcers we speak to know a deal when they see one. The time goes on rebuilding the same calculations, the same area research and the same pack, again and again.
Spreadsheets that drift
Every deal is run on a copy of a copy, with old tax rates and assumptions nobody remembers changing.
Area research by hand
Sold prices, rents, energy ratings and flood risk each come from a different site, and the research starts again for every deal.
A pipeline nobody can see
Leads from agents, auctions and direct approaches sit in messages and notes, so the best deals are not always the ones that get chased.
Investor packs rebuilt by hand
Each pack is put together from scratch, so the numbers in the pack and the numbers in the analysis do not always match.
What we build for investors.
One set of numbers from the first look to the first rent, so the analysis, the pack and the portfolio always agree.
Know the area before you offer.
BozApps grew out of Bozmaps, a UK mapping studio, so area data is our home ground. We build maps that put official prices, rents, energy ratings and risk around the postcodes you are watching.
Sold prices from HM Land Registry for nearby streets, filtered to the same kind of home.
Average rents for the local authority, by number of bedrooms, from the Office for National Statistics.
Energy certificates from the official register, plus flood risk and planning designations from open government data.
Every property in your pipeline pinned with its numbers, so patterns across areas are easy to spot.
The rules that move the numbers.
Tax and regulation change what a deal is worth, and some of it changes again soon. A few of the rules the analyser and your records are built around, in England unless stated.
Stamp duty surcharge on additional homes
Buying an additional home in England or Northern Ireland means stamp duty at 5 percentage points above the standard rates. Wales and Scotland have their own taxes and surcharges.

Making Tax Digital for Income Tax
Landlords with qualifying income over £50,000 must keep digital records and send quarterly updates from compatible software. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028. Updates are due on 7 August, 7 November, 7 February and 7 May.

New tax rates for property income
Property income will have its own rates of 22%, 42% and 47% from 6 April 2027, and mortgage interest relief will be given at 22%. Scotland and Wales can set their own rates. Checked before the Budget on 28 October 2026.

Minimum energy ratings
Rented homes in England and Wales must be EPC band E or better unless an exemption is registered. The government has decided to raise this to band C for all tenancies by 1 October 2030, with a £10,000 cost cap per property, but the regulations are not yet law.

Renters' Rights Act: the new tenancy system
Most private tenancies in England became assured periodic tenancies with no fixed end date, new and existing alike. Section 21 no-fault evictions ended, possession now uses section 8 grounds and Form 3A, and new tenants must get the key terms in writing.

Private Rented Sector Database
Landlords will register themselves and every let home, with gas, electrical and energy certificate evidence. Regions are planned to open in turn, from the West Midlands on 15 December 2026, with London from 15 July to 14 October 2027. The regulations still need Parliament's approval, and the government's planned fee is £65 per property per year. The landlord starts each registration, and an appointed letting agent can supply the property details.
Anti-money laundering checks for agents
Estate agency businesses, including property finders, must register with HMRC for money laundering supervision before trading and check buyers and sellers. Letting agents are covered for homes let at £10,000 a month or more, a threshold that changed from euros to pounds on 30 June 2026.

Redress and client money protection for agents
Anyone doing lettings or property management work for landlords in England must belong to a government-approved redress scheme, and agents who hold clients' money must be in a client money protection scheme. Estate agents dealing in homes must belong to a redress scheme too.
