In LA, it can range from 90k-180k depending on who you ask for a ground up ADU.

With the 600 taken it out it generally says in the 200k range at the end of the year.

If you do plan to flip in that price range you're going to need an intimate knowledge of the area, demand drivers, and how to remodel these older homes efficiently. 

An example would be buying a SFR house in a Class B area for 230-250K that is renting for 1600-1800 range, those are not home run numbers but with low property taxes these are still better deals than what you find in other places.All the best in your search!

Odds are there is a Exclusive right to represent where they are bound to the agent and they have to pay, so they just go look elsewhere.

I'd try to stay to the smaller homes somewhere in the range of 1500sqft or less. 

I'm hunting down pre-foreclosures to flip (my backyard is in the $250k-$450k+ range), and then putting that cash in a neighborhood in southern CO with lower property values that cash flow.

It will likely be in the 7-9% range for an investment property. 

When buying my first property, what price range would you recommend? 

You need a massive marketing budget, and you need to double close on the property, meaning you need the actually have the cash to buy the place.Flipping contracts from unknowing sellers to buyers is a shady business, illegal in most states, and has a failure rate in the high 90% range.
