Your marriage is an investment also.   

However, you won't likely be re-selling anytime soon if you do purchase and fail to get the heirship issues addressed prior to purchase.I suspect, there may be more than 2 heirs (marriages, children, etc. all come into play for each heir) but you'll need to speak to legal counsel to determine if the risk is worth the reward.

Do you make them submit a marriage cert?

My personal belief is that once marriage and kids come along, a portion of this large demographic will be looking for more space.  

I'm in a multiracial marriage, I don't just assume people are racist because they like a flag.

c)  Lastly, don't partner with just anyone, this is almost going to be like a marriage for you, and that person has to be trustworthy of being able to work with you. 

I’m an outspoken proponent of marriage and the importance of all children growing up in a nuclear, intact family.

If I did that for six months I'd basically be flushing my marriage down the toilet bowl.

Keep in mind that partnerships are like marriages, so get to know these potential investment partners on a personal level.
