All of the economics have to be right.

Too many people are sleeping on this.Kentucky Economic Development has many site ready properties in smaller areas that are ripe for rentals. 

However, after further research, I’ve noticed that Charlotte, NC, and Raleigh-Durham, NC, are experiencing robust rental market growth and expanding economic opportunities.

It's important to stay informed about developments in the areas you're considering, as well as any potential changes in regulations or economic conditions.

It would be hard to cash flow on a 600k house that has 3600 in rent regardless of the broader economic situation going on in society. i find that when someone says BRRR doesn't work anymore they end up meaning it doesn't work well for the specific types of real estate that they want to buy.

The Agreement should have a clause that buyer can cancel without penalty and with full refund of the security deposit if the signed letters are not returned to it by a certain deadline, or if subsequent tenant notifications materially change the economics of the deal.

In my market, which is a fairly economical place to build, I am friends with full time builders that are in their properties about $150k/door for construction level finishes.  

.- Someone talked about crime and hard tenants (who don't pay - usually inherited ones)- not many economic opportunities to attract pool of people and boost area etcI'm looking at houses on both sides (Canada and USA) US, they are cheaper like 731 Pine Ave, Niagara FAlls NY 14301 going for $270,000 (5/2, 2700sq ft) but on Can side, it's like houses are in the US$400K - smaller sq ft.

Some times in between there in rougher economic conditions it was getting unexpected vacancies. 

You need an income that meets three requirements:Rents increase faster than inflation to offset constantly rising prices.It must be reliable; it continues even during economic downturns.It must last throughout your lifetime.These are all long-term requirements, so the current interest rates are not the major issue.
