What It Is

InBest is a free Chrome extension. Rather than a traditional marketing or SEO tool, it is positioned as an auxiliary analysis tool for real estate investment. It is mainly designed for users browsing residential properties for sale on Idealista, helping them quickly assess the potential rental return of a property after purchase.

Core Features and Data

Once installed, users will see a red button next to the price on an Idealista property detail page, showing the estimated rental price, gross rental yield, return on investment, and annual cash flow. Clicking the button opens an advanced calculator where users can manually adjust the calculation values. Users can also set default parameters from the Chrome extension icon, including mortgage interest rate, loan term, down payment ratio, and annual expenses such as community fees and insurance.

Its rent estimation logic is fairly straightforward: it multiplies the property’s square meters by the average rent per square meter in the area. The page clearly states that this is only an estimate and may not reflect the actual market situation. The text does not disclose the source of the average rent data, sample size, coverage, or update frequency, so the results are better suited as a preliminary screening reference rather than a basis for final investment decisions.

Pricing, Platform, and Support

InBest explicitly states that it is 100% free and can be downloaded from the Chrome Store. The page does not mention subscriptions, paid plans, or enterprise editions. The currently supported platform appears to be only a Chrome extension, and its use case is tied to Idealista. Contact channels include Telegram and email. The tool collects users’ email addresses to notify them of product updates and states that it will not share them with third parties.

Pros and Cons

Its strengths are that it is free, lightweight, and embedded directly into property pages, reducing the time users spend manually building return models. It also allows adjustment of key financing and expense parameters, giving it a degree of flexibility. Its limitations are that the data methodology is relatively rough, as actual rents are affected by many factors such as floor level, renovation quality, orientation, supply and demand, and regulations. In addition, it is built around Idealista only, with no visible support for other portals, mobile devices, APIs, or team collaboration features.

Who It’s For and Access from China

It is suitable for individual investors and small real estate investment teams focused on Spanish Idealista listings, especially for quickly screening potential rental investment opportunities. The text does not provide information about access from China. Access to the Chrome Store and Idealista from mainland China may be affected by the network environment, so actual usability should be tested individually. Since the tool is free, there are currently no cross-border payment issues. Alternatives include real estate yield calculators, Idealista’s own information, Rentometer, AirDNA, and similar tools.
