@Alexandria Harden the best way to add value would be to lower expenses or raise income (rents).

@Alexandria Harden You can make 5 different offers per week without having to have multiple out on the street at the same time.

You might consider “hardening” your properties, and you’ll find many threads on that topic.  

Now, multifamily will be a little less desirable than single family, and there are a lot of new apartment complexes you might be competing with, so make sure your finishes are nice and you "harden" your rentals.  

They are lucky to have a good landlord.When the reverse happens tenants become hardened and no longer contribute towards a property.

And the surface was hardened. http://s284.photobucket.com/albums/ll8/maxc2010/3060%20CR%202182%20Greenville%20TX/?

Good idea for a thread, but it's been posted previously; just a couple of them here:http://www.biggerpockets.com/forums/52/topics/68041-how-do-you-harden-your-rentalshttp://www.biggerpockets.com/forums/52/topics/51199-making-your-rentals-durable-Many other threads exist on specific items, like flooring or plumbing.

These areas can require some advanced management techniques and hardening of the properties.

Heres a really good discussion on hardening/bulletproofing rentalshttp://www.biggerpockets.com/forums/52/topics/68041-how-do-you-harden-your-rentals

I typically harden/ replace any items that need to be taken care of prior to putting a rental in service to avoid future headaches.
