Don't be afraid to do it. It's a common occurrence. You just need to have the knowledge and the right people around you.
1. Work with proven experts. Make sure that the experts have a process for reviewing the property - both the numbers, the area, and the 'street' knowledge (i.e. on the ground talk).
2. Ask who is buying he property for you, if they are buying or have bought themselves in these areas.
3. Do your own due diligence on the property, street, area.
4. Have someone do a video walk through and photos of the property. Also check out google maps. You might detect changes that you should consider discussing.
