SI'S PROPERTY ACADEMY
THE DEAL ENGINE

Run the
numbers
like a pro.

Sound familiar?
"I don't know what I should pay for it."
"I've no idea what the refurb will cost."
"Is it even a good area to invest in?"
This answers all three. Put in:
1The postcode of a deal you're looking at
2What you think it's worth done up
3A rough refurb level — light, medium or heavy

…and we'll tell you the price to buy at, whether it stacks up as a deal, and back it with the data on the area — prices, rents, growth, schools, crime.

Spotted some deals and want to test them? Picked your patch and want to understand the prices and rents before you offer? Either way — start here.
