This is purely anecdotal, but in my experience, proponents of the 'HF creates slums' theory tend to fall into one of two camps:

- functionally blind

- landlords

The functionally blind (note that I'm not saying 'sight impaired...this is by design) tend to argue that homelessness is okay...as long as they can't see it. Often, they live in cities like mine (Regina, Canada) where for 3-4 months of the year, it is too cold to sleep outside. Because of this, homelessness in these cities often involves a mishmash of shelters, crashing on various couches, and sleeping in malls during the day/hanging out in coffee shops at night. The rest of the year, whether through policing or civic design, 'homelessness' consists of guerilla camping in parks and other out of the way places. HF does tend to make homelessness more visible. Programs generally start with a marketing campaign designed to attract landlords, then word gets out on which buildings house the formerly homeless.

And, that's when the functionally blind start to complain. Often, the complaints take the same form as people who protest against halfway houses opening up in their neighbourhoods. They print up flyers decrying the 'death' of their neighbourhood, and show up at city council meetings. Later, they seize onto minor crimes (ie - my sister's former roommate's cousin's veterinarian had her purse snatched two blocks from that building) to justify their beliefs.

Landlords are in a more precarious situation. Since HF does not have its own housing, it absolutely requires the support of landlords. Some HF programs are not terribly well funded so, while they guarantee that rent will be paid, they often require some form of discount to be financially feasible. That alone is a strike against them, at least from the perspective of business.

But, if you are a landlord and are willing to work with HF, you have a difficult choice. Realistically speaking, HF candidates have issues which create homelessness in the first place. Candidates often suffer from severe mental illness, chronic addiction, and health problems. They aren't always capable of basic upkeep in suites. So, do you offer up, say 15 suites in one building to the program, or do you spread the suites around multiple buildings. Some landlords have reported that the buildings that house HF candidates are more difficult to rent out and that the rent for all of the suites has to drop accordingly. This is one of the biggest reasons that landlords drop out of the program!
