Good one Y-man!
When I was single, investing used to be very straight forward and easy. Since I got married, I used this strategy:
1. Choose a few potential IPs, visit the sites myself and I do all the research first on which is a good investment. I do not tell my wife at all about my research and results.
2. We go check out all the IPs together as though it's our first time.
3. She puts in her 2 cents. This is important as you need to give her a chance to voice, emotional or not and I have learnt to "play along".
4. If she chooses one which the numbers / elements don't add up, I may play along at first or I put my foot down straight away depending on the situation.
5. If she chooses one which makes $ and sense, then we have consensus.
Either way, the $ and sense will prevail. Until today, she still brags about a couple of IPs which we bought and she thinks that it's her good investment judgment because of the aesthetics and design of the place or close to the beach, whatever the case may be!
I have also learnt that a woman balances the softer and warmer side of an IP which a man sometimes cannot see. This can be potent complement to the process as long as the key principles of investing are followed. Like it or not, there are still huge number of couples where the wife's decision to buy is a big factor, and women see the same things! Developers and sellers also know this and dress up the property according to their taste sometimes. I try to look beyond this and take the bare walls as they are.
I say do the work behind the scenes and let her have the glory.
