The environment now with higher interest rates and higher purchase price does make it more difficult but definitely doable. 

These areas might have higher property prices, but they can offer premium rental rates and higher occupancy.

(Maybe the seller has a great interest rate, but you would have to pay twice that amount which wouldn't be profitable.)11) Crime in the neighborhood. 12) High turnover in tenants (raising your expenses.)

I think your correct though folks have to adjust to the new normal and the interest rates they are not coming down like folks hoped for I think we are in for a run of years were rates will be more like the 2000s  6 to 7% and Owner occ in the 5s with Maybe some high 4s. but by the time folks wait for that prices will rise in the better markets.

I'm a Realtor with a couple properties listed in Boise, ID and a neighboring town for my investor/client that are currently rented as co-living or rent-by-the-room and getting killer income. (7.3% - 9.5% Cap rate) So far, every inquiry has been baffled by the concept of co-living or rent-by-the-room and immediately ask if they're being run as a halfway-house (which they are not).

And the values like all rentals will just track the rental rates and what an investor is willing to pay for a return.

For your $2M property, a cost segregation study estimates $316K in first-year depreciation (compared to $28K with standard straight-line), potentially saving ~$117K in taxes at a 37% rate.

Who cares about lifetime interest costs, except to the extent you can easily lower them (refinance to a lower interest rate) to increase your cashflow.

The landlord shall not commingle such moneys with any other funds of the landlord or hypothecate, pledge, or in any other way make use of such moneys until such moneys are actually due the landlord;(b) Hold the total amount of such money in a separate interest-bearing account in a Florida banking institution for the benefit of the tenant or tenants, in which case the tenant shall receive and collect interest in an amount of at least 75 percent of the annualized average interest rate payable on such account or interest at the rate of 5 percent per year, simple interest, whichever the landlord elects.

Brandon Turner's Rental Property Investing book is an excellent primer to understanding the happy path for purchasing a property - however in this market it really comes down to having bulletproof assumptions on rents/taxes/R&M/etc. as with rates as high as they are/inventory as low as it is, there is less cushion in your returns if you analyze properties with bad assumptions.
