I'll echo what Stephen said, insurance makes things tricky as well as the high interest rates impacting the rest of the country, but if you get a good enough deal you can maybe make it work.

We manage vacancies for a lot of out-of-state and out-of-country landlords.

The home value decreases are not as bad as I wrote country-wide, however BC and Ontario have taken a heavy hit as discussed and they represent over 50% of the population.

Above 5+ units is possible but more challenging and rates are where you would expect them..50-65%LTV will be common for higher plex units, a common workarounds is if they have a US based family member or business partner with an LLC..Some investors or lenders have specific countries of origin that are restricted or even prohibited, check with your mortgage professional. 

@Ali Boone RP Capital is a company that finds deals (turnkey) in various areas of the country.

They are located in Hot Springs Village, one of the largest gated resort communities in the country.

I don't want to say too much on public forum but, MN is high income state, which makes for some of highest median incomes in US, which makes for some of the highest paying sec8 in country..... 

In short, they are creating bird dogs with their programs throughout the country.

FL is also the toughest state in the country (based on my experience) for reliable contractors.If you don't need a ton of house, you could find a nice option for yourself and try to get a small rental.

Like Joseph mentioned the southern/middle part of the country is great because the price points are much easier and the laws are landlord friendly.
