There are a few homes in the 215k-230k range if that makes you more comfortable, but you usually get what you pay for.The price of your first rental should be what you can afford and fits your investment strategy.

There were 17 active listings ranging from $374,900 to $704,400.

These times can range from normal times like 9-10pm to later times like 1-3am. 

The costs can vary widely.  

From my research, I didn't think there was any magical rent formula but I was hoping there were some generally accepted guidelines that would put me in the range. 

In looking for a manger I see that there is a wide range of maximum repair value that the management can authorize without my authorization.

It is going to be tough for you to find a high LTV conventional loan through a bank or credit union with a property in that price range.

I think I could 1031 each of the duplexes into a newer 2000s later build SFH in the 185-200k range and mitigate a lot of the vacancy/capex issues I’ve been having w the older duplex units.

My listed rents are in the average range for the market they are in. 

@John MatarazzoAs a US citizen, you are required to report world-wide income.Rental income is not 'earned income' per FEIE purposes.Yes, you are required to file a tax return and report the rental income.You may be eligible for some credits for taxes paid to a foreign country.Read the tax treaty between the US and the other country taxing you.
