This is a very good article with some great ideas for working as a couple to buy a home.
Buying real estate can be a challenge emotionally alone and even more difficult as a couple. Negotiation with the seller, AND your partner.

The article gives some very practical ideas for helping each other through the process:
Get pre-approved. This is a big one. It’s also, in my opinion, the least fun-but perhaps the most important. This is the opportunity to flush out the financial issues, look at your budget and have clear picture of your price range. It’s heart-wrenching to find the right home and then figure out that you can’t afford it.
Work together to come up with the must-haves and the nice-to-haves. Buying property, even with lower property values, is expensive. Everyone has a limit-which means setting priorities. Knowing those priorities really helps you sort out the possibilities.
Get on the same page. This is also really important. There’s nothing more frustrating than finding your dream home and your partner doesn’t think so. There will always be properties that one partner likes and the other doesn’t-BUT, if you have a clear picture of the priorities, this will get reduced.
