Customer testimonials


Another sale saved thanks to Alex McDermott and his team at Upstix. As an agent I work with vendors who find themselves unable to secure their new home because they can’t sell fast enough or are at risk of losing their purchase because their sale has fallen through. Alex has personally just gone the extra mile to ensure that one of my clients can complete in time to buy their new home. Alex offered the highest price of any fast buy company and worked tirelessly to get the deal across the line in time. Thanks Alex, I know I can always rely on you to save the day!

Amazing service. Jeremy has been so helpful with our house sale. I was in tears thinking we would lose our dream home and he did everything he could to make sure it could happen for us in the quickest time possible. Can’t thank you enough.

From my very first contact with Upstix. From my very first contact with Upstix, everyone was polite and so helpful. The communication received from Kris was second to none. He always called when he said he would or if he was unable to would ensure one of his colleagues kept us updated as to what was going on. We felt that everyone was on our side and rooting for us to get the best possible outcome. Upstix have enabled us to be able to offer on our forever home and we are so grateful to Kris and his team for all of their help and support.


Great is quick and easy is what your looking for. Kris and Charmayne have been great at keeping us updated and pushing things along for a quick sale. We exchanged in just over 3 weeks as they expected.The price didn’t drop once agreed after the survey, so a hassle free option if easy is what your looking for.

Are flats harder to sell?

Selling flats can be more challenging compared to houses due to factors like lease terms, service charges, and market demand. Flats with shorter leases or in less desirable locations might take longer to sell.

However, we offers a solution by directly purchasing these properties if they match our criteria, typically within 7 days.

What will UPSTIX offer for my flat?

We are prepared to offer up to 87% of your flat's worth. This amount is intended to encompass all expenses and fees related to acquiring, maintaining, and disposing of the property. Moreover, we take the potential risk of the property selling for a lower price than expected.

What is the fastest way to sell a flat?

The fastest Upstix can buy a flat is within 7 days, subject to it meeting our requirements.

What flats sell fastest?

Flats in excellent condition and priced correctly sell the fastest. This is because well-maintained properties and competitive pricing attract buyers quickly in the UK's property market. Essentially, the key to a swift sale lies in presenting a flat that meets buyers' expectations in terms of quality and value

Should I use a real estate agent?

Deciding to use a real estate agent involves considering the speed of sale and desired price. The 2023 trend showed properties often listed 27% higher than their selling price, highlighting a gap between expectations and market realities.

This can extend selling times, with properties typically taking six months to sell through an estate agent.

Is it possible to sell a flat with tenants in it?

Landlords typically cannot break a lease just to sell a property. However, we can purchase properties with tenants in place, adhering to existing lease agreements. Our expertise in handling such transactions ensures that both the landlord's and tenant's rights are maintained throughout the process.
