When a MF unit stays on the market is that a red flag?

[Ashley Wolfe]

Hello,

I've noticed two particular MF properties in the FT Worth area that have been on the market for approximately six to eight months.  One is a 4-plex, one is an 8-plex.  The 4-plex is listed for $189,900 and the 8-plex for ~$289,000.  When properties like this stay on the market without being snapped up by investors, should this be a red flag that there is more going on than meets the eye?  If these properties are both in C/D areas, is that an automatic red flag as well?  I thought that going into a C class property and rehabbing it to a B is one of the most common investing strategies.  So why are these still sitting there? (Sorry for the wonky formatting.)
