Same 3% inflation for selling = $134400 for 1 house or $672000 for 5 houses.

Moving to Colorado Springs and trying to make a sound investment but seems that all of these homes are over inflated.

They will give you inflated sales numbers that are inaccurate to actual profits.

With rapid economic expansion and population gains slated to keep demand healthy, Yardi Matrix expects rents in Dallas-Fort Worth to rise 4.3 percent in 2019.

What is the chance that a rundown property like this can still appreciate and rents can still rise?

I am interested in a condo in a high-rise on the beach.

Any houses built prior to 1995 will be limited to a 6% rent increase per year plus inflation. 

With inflation everything cost more year after year

Presumably the reason is that it takes many years to assemble several contiguous parcels needed to do an efficient high-rise redevelopment . 

As high as this market is right now, I think we (as a collective society) will continue to over-inflate housing prices - so really we're in an appreciation market... that is, until the bottom falls out.Tech jobs are huge here.
