Daniel Walker , i totally get where you are coming from on this topic. Living in Fort Collins, the way the market has appreciated over the last 3 years has made people do some things they might not otherwise and ask new questions because the market has compressed buying so much and giving homeowners a new found confidence.
While I do agree with most on here that it would be a bad idea to take on negative cash flow every month, i disagree that town homes are a bad investment option. In fact, I feel in a lot of ways they are a better investment option than SFHs in a city you live in because you can manage it yourself and "save" money on property management.
I am a Realtor here in town for Velocity Real Estate and Investments and I own a couple of rentals myself. Did you know that for single family homes, average sales price grew 6.8% YoY vs LY but for Condos/ town-homes the average price grew 27.8% vs LY.
My company specializes in investment opportunities. If I can help you in anyway, let me know. Good luck!
