Don't get me wrong; there are plenty of issues/problems/quirks that old houses have that new houses don't, and an old house can obviously have hidden problems and big repair/maintenance bills too--which is why thorough due diligence is fundamental to REI...but, the point is: a brand new house is not a foolproof solution to repairs/maintenance headaches (and in some cases, a brand new house can be a much bigger gamble than an older house).This is a particularly important lesson for inexperienced investors, who tend to be the most prone to "shiny object syndrome" (the tendency to let nice aesthetics distract from real, underlying issues).

We are focusing on Phoenix due to the perceived strong fundamentals, diversified economy and relative affordability to purchase multiple assets over the next couple years.

But fundamentally, what is being taught is the same.

Its important to be well informed about the fundamentals in your market and general REI principles, but at some point every investor has to come to terms with the fact that we can never know whether markets will go up or down, and not knowing cannot prevent us from taking action if we want to achieve our investment and financial goals. 

Not fundamental flaws in an overblown market.

@Colleen F. it's similar but also fundamentally different in several ways:1) OpenDoor is already charging a higher fee just for "privilege" to sell TO them2) OpenDoor's offer prices are usually lower than market prices3) It can be confusing to both consumers and agents, because OpenDoor is operating similar to a wholesaler in that they claim to close quickly, with cash, and make the sale process easier on the seller.

What are the Las Vegas fundamentals that will maintain the growth of property values and rental rates?

Fundamentally I hate debt so I have an internal struggle with not accelerating debt payments even though I know it may be smarter or more efficient to keep the cash ready for future investments.
