Checklist: Criteria for Your Real Estate Investment
With our 11-point checklist, you are well prepared for your real estate purchase:
Real Estate as an Investment vs. Personal Use
At the beginning, the question is clear: Do you want to live in your property yourself? Or do you want to rent out your apartment as a rental property after the purchase? You should think about this at the beginning. After all, this affects not only the financing. As an owner-occupier, you are still responsible for the operating costs after acquiring the property. However, if it is a Real Estate as an Investment, these costs are mainly covered by the tenant and the tax office.

Price of purchase: Factors
Equally important is that you set a maximum purchase price for yourself. Here you should take several factors into account. These include your creditworthiness, available equity, as well as your loan-to-value ratio.

Maximum Gross Rental Yield: Formula
How high must the rental yield be at a minimum for the investment to be profitable and paid off by the tenant? For this, we recommend the following formula:
Formula: Annual rent / purchase price * 100
Investors pursue a primary goal, efficient wealth building. Accordingly, the gross rental yield of a yield property must be high. Learn more here:
Rent out or buy vacant?
Of course, you can buy an already rented property just as easily as an unrented one. However, if you are purchasing the property for personal use, an unrented property would definitely be more advantageous. If there are already tenants in the apartment, you can terminate the lease for personal use after purchasing the property. Something similar applies to investors. On the one hand, you save time by not having to search for new tenants, but you are simultaneously bound to the rent. So, should you buy a rented or unrented property? Find out all the advantages and disadvantages here:
Location, location, location!
Not only the city is important, but also the neighborhood. Where is the nearest hospital? How is the connectivity? Are there a lot of vacant properties in the surrounding area? And how safe is the residential area? All of this affects not only your local living experience, but also the value of the property and the purchase price. What exactly does A-, B-, and C-location mean? How is it determined and how does it affect the purchase price? Find out more here!

New construction or existing property?

The differences between existing properties and new construction, as well as the respective advantages and disadvantages, can be found here:
