If you can't in a glimpse, you should consider replacing or changing the size to make it appealing.

I would think that you would have to do an equity split with someone to make it appealing.

The other plan was to rent my house outright, but rentals in my area aren’t quite cash flowing where it would make sense, which is my short term was appealing.

I have decided that buying and holding and the BRRRR strategies are most appealing to me.

Although it's been two months since I closed on the property and three of the units are rent-ready (excluding the one that is currently occupied), my property manager and I are simply not garnering enough interest for each 3 bedroom/2 bathroom unit at $650.00/month.The building itself is only 43 years old and has recently gone under significant remodeling so I would think there is more appeal than a run-down, poorly managed building.Can someone please advise what else we can do to get a few more vacancies filled?

We have one (1820's 6b/5b mansion) that the tenants & prior tenants are convinced is haunted but tenants have all been long term. look at this write-up that appeals to the realm of 'scary'.

I have good news: The steps you need to take to be appealing to other investors are the exact same steps you need to take to be effective here on BiggerPockets.

Or any other suggestions on the best way to get the curb appeal?

Without seeing it, it is difficult to tell you but I think you could offset the cost with landscaping and curb appeal. 

I'd suggest figuring out how to get into some work yourself, even if it means taking on something less appealing initially as a project.For that contractor (that's any good) they don't want the risk that they're wasting their time going out to walk a site that may or may not close, or that you may or may not actually use them on...Most that are any good aren't contractors anymore, by the way.
