When loans were called, was it due to specific triggers like delinquencies, insurance lapses, or low-interest rate portfolio loans held by smaller banks?

However, the rental value this area is very low compared to the Home values and mortgage rate.

It's definitely possible to get a loan as a foreigner but the rates will be high(er) and the downpayment required will be as well.

I'd wait this one out until rates lower and you can refi and learn from it to buy better the next time around. 

There are short-term rental management companies that can help with that.One that I work with in Michigan covers the entire state and can advise on local short-term rental regulations or regulations that may be on the way, they can give you an analysis of the demand for short-term rentals in that area, nightly rates in that area, monthly occupancy percentage, and projected monthly income.They also let you choose the level of service you would like from them from full service to minimal.To your success!

@Iris Olivas Most local banks/credit unions can do this deal with lower fees and potentially rates than brokers.

If you house hack a single family residence by renting out  a room or two then you would have no property tax but if you buy a duplex you might have to pro-rate the property tax.  

That worked well when rates were 3.5% but that "strategy" no longer exists.

Even though interest rates are high, we have a big Mircron plant coming here as part of the CHIPS act so that could boost housing demand in the coming years.I don't know the SYR market, but I did a quick search for duplexes somewhat outside of the city, and found this: https://www.realtor.com/realestateandhomes-detail/7300-Lakes....

Once you are an experienced investor and know rental rates and costs you can provide value to clients.
