Investment Property

A person who has an investment property is someone who is in a relationship with someone who is undergoing a huge make over/glow up. The investor enters a relationship with someone that is below a 10/10 in the hopes of their partner eventually transforming into a 10. Hence why they are investing into the relationship market while the demand for their target is low
