Entrust us with the estimate and sale of your housing property

To be able to sell your property, it is essential to properly estimate your residential property. For this, it is necessary to consider certain steps. Open Up helps you to evaluate your property which is a key element to sell in the best conditions.
Different criteria are considered in the valuation of a property. First, the nature of your property: apartment or house and its state of occupation. Of course, the architectural quality and general condition of it is also very important: the type of heating, its age, its area, the number of floors, rooms as well as the exposure and its location are elements which will be decisive.
In any case, to be able to estimate your property at best, it is necessary to evaluate its weak points and its strong points. How? starting from the average market price, all you must do is analyze your property and if it has advantages then it will be overpriced and if it is the opposite, it will be underpriced.

1 - A justified price

It is important to have a real vision of your property. So be careful not to overestimate or underestimate this one. Indeed, a seller has a habit of overvaluing his property because of the affection he has for it. This often seeks to make a profit. Conversely, the buyer is more likely to undervalue a property by finding the slightest defect, to better negotiate the price.
The real estate valuation is also impacted by demand, it depends on the expectations of the buyer, and these are unpredictable. Your property may be invaluable to one person and passable to another.
To know if your vision is right, just take the happy medium. This will give you a certain estimate which you can check with the market price.
Good to know: if you manage to find the right price, your property will sell within 85 days on average depending on its location.

2- Environment and location, important factors

To correctly estimate your property, be aware that its valuation per m2 may differ from one street to another and even from one building to another. Within the same perimeter, one can truly observe considerable price differences.
The notoriety of the district and its frequentation are elements to be taken into account. The resulting feeling of security is not insignificant. Thus, if your property is in a residential area, close to public transport and shops or if it is located in an insecure part of the city, the estimate will be different.
All these elements have an influence on the estimate.

3 - The intrinsic characteristics of your property to take into account:

- The quality of construction and renovation depends on the nature and choice of materials used: noble materials such as stone and granite - light or poor-quality materials should be taken into consideration. The level of requirement for a renovation depends on the characteristics of the property. It is recommended to keep a certain consistency in terms of space optimization plan and choice of materials. Open Up advises you in terms of renovation from the purchase of your property.
- The state of maintenance of your property is a determining factor to consider in the evaluation of its estimate. A neglected maintenance increases the decrepitude of the construction; On the contrary, regular maintenance partly corrects the depreciation resulting from the age of the construction. Open Up offers property maintenance services, thus combating obsolescence and the resulting loss in value due to a lack of regular maintenance when you do not live on site. contact us
- The equipment and elements of comfort are also retained characteristics: Home automation, alarm, air conditioning, safety and hygiene Certain intrinsic characteristics come into play in the calculation of the price. The presence of a swimming pool, a balcony, a garden, an outbuilding... Will have a real positive impact on its estimate.
- The class of the building: The state of maintenance of the common areas and the architectural character of the building are to be considered.
- Legal factors: architectural easement, right of way, state of occupation of the building, listed building, etc. Do not neglect to inform on these essential points.

4-EPD (Energy Performance Diagnostic) and Standards

It is sometimes necessary to seek the advice of a professional to correctly estimate the cost of possible renovations. This quote will make your sales request more serious in the eyes of potential future buyers, so your property will be even more attractive. Without this indication, future buyers risk considerably wanting to lower the selling price, especially when your property needs upgrading to new electrical standards and when the EPD is not in the right category.

Indeed, a new, more restrictive classification system was put in place on July 1, 2021. The EPD is a mandatory diagnosis that classifies your apartment in terms of energy performance and greenhouse gas emissions. It is important to follow the evolution of the laws in force.
