Nights, weekends, holidays, etc.To keep this on-topic, though...DO figure out what's healthy for you to manage but remember it's a process where every experience teaches you good and bad (and be patient with that process).DON'T sweat the small stuff (damage/costs under $50, undisclosed dogs, etc.) but DO find a way to learn, prevent, put in better practices to maintain your sanity. 

Sadly there’s a lot of bad actors out there peddling similar courses and schemes.

You may want to first explore cities that you are already familiar with.Think of cities where you grew up, went to school, like to vacation to or see family.You will have a better idea of what the good / bad parts of town than a brand new city that you are unfamiliar with.Best of luck.

Gas heat would require constant tank refilling and it would be very bad to run out in the winter.

Not too bad when the inventory is low, the number of sales is low (like a 30 year low), interest rates are high and prices are high. 

To be fair, I'm not saying inexpensive properties in the Midwest is necessarily a bad way to invest but I think it's better for people who live there who can be hands on with the property. 

$150/mo - $300/mo is bad or good cash flow depending on how much cash you put into the deal.$150 x 12 months = $1,800If you put $45,000 into real estate as a down payment, you are looking at a 4% cash on cash return.I would consider this decent.If you put $20,000 into the deal, the cash on cash return is higher and its better.If you put $200,000 into the deal, the cash on cash return is lower and considered worse.However, cash on cash return is not the only return you should consider, you should also consider appreciation.My benchmark is trying to achieve atleast an 8% return between appreciation and cash flow.Best of luck!

Hope is a bad strategy.The only on market strategy that I think can work is paying cash/line of credit/hard money for a property that does not qualify for conventional financing.

Great question - Renovation is where things frequently go bad.

They’re making sure they are aware of anything bad happening or issues they need to be aware of.
