I'm not a huge fan of constant buying and selling - it's just too much damned work at this point in life - but for sure I would jettison anything that wasn't making an acceptable profit, and if you have any RE you should know this number. 

Michael,   A good book to purchase is "Professional Real Estate Development: The ULI guide to Business.   

My wife briefly help a friend manage their monthly short term rental in San Francisco while they were traveling and have a few friends that do it.Monthly rentals seem to book pretty well, but not at a significant premium to long term term rentals. 

Then you can read a more in-depth book like The Book On Rental Property Investing by Brandon Turner or The Unofficial Guide to Real Estate Investing by Spencer Strauss.2.

They prefer to purchase a duplex in a C location because they have read a book about the 1% rule and/or the BRRRR rule.

I'm doing tpc compliant texting to motivated sellers to book appointments. 

Would recommend you read a couple books about BRRRR, that will give you the basics and then feel free to reach out.It remains a great strategy, but you have to manage your expectaions.

But i am here to learn, one day at time, one book at a time.  

How can I get bookings in this type of environment in the dead of winter?
