Tool 05 · HMO Roadmap
From accepted offer to a let, refinanced HMO
You’ve found a deal that stacks. This is the long game — the milestones from a handshake on price through finance, legals, completion, the build, compliance and letting, to pulling your capital back out. Tick each step as you go so nothing slips through the cracks on the way to a fully let house.
“The deal is won in the offer; the profit is kept in the execution.”
Your progress saves automatically. Use Saved to keep a separate roadmap for each property you take forward.
Your deal progress
0 of 0 done
Work through the phases as your purchase progresses. Many run in parallel — finance and legals especially — so don’t wait for one to finish before starting the next.
1Offer & instruct0/0
Days 1–7
Your numbers stack — now move. Speed and looking proceedable are what win the deal at the right price.
Set your max offer and submit it?Offer below asking with a reason (works needed, speed, cash/proceedable). Leave room to negotiate up to — but never past — your max.
Anchor it to the figure the Deal Analyser gave you — not what the agent hopes for. Know your walk-away number before you start.
Get the offer accepted & the memorandum of sale
Once agreed, ask the agent to issue the memorandum of sale to both solicitors — that starts the clock.
Instruct your HMO-experienced solicitor
Use the one you lined up in the Action Plan. Conveyancing on a conversion has wrinkles a general firm can miss.
Tell your broker it is on
Kick off the finance application straight away — it is usually the longest pole in the tent.
2Finance0/0
Weeks 1–6 (in parallel)
Lock the money down while the legals run. A clean, well-prepared application is the difference between weeks and months.
Submit your mortgage or bridging application
Full application with proof of funds, ID and the details of the deal and your refurb plan.
Book the valuation
Your lender (or bridging lender) instructs a valuer once you apply — get it booked and pay the fee promptly so it doesn’t hold things up. For a tired property they may down-value or retain funds until works are done, so be ready for it.
Receive your mortgage or bridging offer
Read the conditions carefully — some lenders restrict HMO use, letting or works, and bridging terms differ again. Flag anything to your broker.
Confirm your refurb funds are ready
Cash, a facility, or a bridge — make sure the build money is available the day you complete, not weeks after.
3Due diligence & legals0/0
Weeks 2–10
This is where the expensive surprises surface. Don’t rush it — the survey and searches are cheap insurance against a bad buy.
Solicitor orders the searches
Local authority, water & drainage, environmental — they flag planning history, road schemes, contamination and flood risk.
Commission a RICS survey & specialist reports
A Level 2 or 3 survey, plus electrical, damp/timber and any structural reports the viewing flagged. Quote the findings into your refurb budget.
Solicitor reviews title, leases & restrictions; raise enquiries
Check for restrictive covenants, leasehold terms or anything that blocks HMO use. Resolve every enquiry before exchange.
Confirm the planning route & apply for the HMO licence
Use the Potential Checker’s verdict: permitted development, a CLEUD, or a full application. Apply for the licence — remember it is separate from planning and does not transfer from the seller.
4Exchange & complete0/0
Target date
The point of no return — and then the keys. By exchange, everything legal and financial must be settled.
Agree a completion date
Line it up with your finance and your builder’s start date so the property is not sitting empty and costing you.
Exchange contracts
Your deposit goes down and the date is fixed — you are now legally committed both ways.
Complete — you own it
Funds transfer, keys released. The clock on your holding costs starts now, so have the build ready to go.
5Refurb & convert0/0
Weeks 0–16 after completion
Where the value is made — or lost. Tight scope, fixed prices and fire safety designed in from day one.
Finalise the scope & get fixed-price quotes
A detailed schedule of works priced by your builder — fixed price beats day-rate for keeping control.
Design in building regs & fire safety
Fire doors, interlinked alarms, protected escape routes, sound insulation — get it right on paper before a wall moves.
Works underway — manage budget, timeline & variations
Weekly check-ins, photograph progress, sign off variations in writing. Hold your contingency back for the things you cannot see yet.
Snagging & sign-off
Walk every room with the builder, list the snags, withhold the final payment until they are done.
6Compliance & certificates0/0
Before you let
No room can be let until the house is safe and legal. Get the certificates booked early — inspectors get busy.
EICR & gas safety certificates
A satisfactory electrical installation condition report and, if there is gas, an annual gas safety certificate.
Fire alarm, emergency lighting & fire doors signed off
The grade and category your council’s HMO standard requires — get the commissioning certificate.
EPC assessed & HMO licence conditions met
Aim for EPC C (mandatory for new lets, and for all from 2030). Satisfy the licence conditions and pass any council inspection.
Furnish the rooms & communal areas
Beds, desks, storage and a genuinely usable kitchen/lounge — the spec you priced into your rent.
7Let & refinance0/0
Ongoing
The finish line: full rooms, and — if you are running BRRR — your capital back out to do it again.
Photograph & market the rooms
Good photos on SpareRoom and with your agent. Lead with the things tenants here pay for (ensuites, bills included, location).
Reference tenants & move them in
Right-to-rent checks, references, deposits protected, tenancy agreements signed.
Reach full occupancy & set up management
Every room let, and a clear plan for who manages it — you or an agent.
Commission the post-works valuation & refinance
For BRRR: a higher valuation on the finished HMO lets you refinance and pull your capital back out. This is where the model pays off.
Review the actuals against your Deal Analyser projection
Compare real costs, rent and refinance to what you forecast — the single best way to get sharper on the next one.
From offer to let HMO
Work through the seven phases above as your deal progresses. Your key figures are captured here as you go.
One step at a time. A first HMO purchase and conversion typically runs three to six months from offer to first tenant. Things will slip — a slow searches result, a build overrun. Keep the contingency intact, keep the team talking, and keep ticking the steps off.
