The following happened to me with Vagrant 2.0 and VirtualBox 5.1.28, though I expect that it affects earlier versions of Vagrant, too.
When using DHCP with NFS, your initial vagrant up might like this:
[...]
==> default: Checking for guest additions in VM...
default: The guest additions on this VM do not match the installed version of
default: VirtualBox! In most cases this is fine, but in rare cases it can
default: prevent things such as shared folders from working properly. If you see
default: shared folder errors, please make sure the guest additions within the
default: virtual machine match the version of VirtualBox you have installed on
default: your host and reload your VM.
default:
default: Guest Additions Version: 5.0.18_Ubuntu r106667
default: VirtualBox Version: 5.1
==> default: Configuring and enabling network interfaces...
NFS requires a host-only network to be created.
Please add a host-only network to the machine (with either DHCP or a
static IP) for NFS to work.
Note message about version of Guest Addtions and VirtualBox not matching. Turns out the command line tools in VirtualBox 5.1 have trouble reading the values of a VM with the 5.0 additions. I discovered this after much digging around in the debug logs (enabled via VAGRANT_LOG=debug vagrant up).
With the VM left in this half-configured state, you can see that vagrant was having issues retrieving the IP address:
$ VBoxManage list vms
"test_default_1507227139063_25909" {fa3f0bd6-c8ee-4e27-915d-2fe4358dab9f}
$ VBoxManage guestproperty get fa3f0bd6-c8ee-4e27-915d-2fe4358dab9f /VirtualBox/GuestInfo/Net/1/V4/IP
No value set!

Notice the lack of properties -- specifically, the IP address for the host-only network adapter (/VirtualBox/GuestInfo/Net/1/V4/IP)iwe're looking for is missing.
Sensing a issue between VBoxManage and VBoxService in the VM, I decided to install the vagrant-vbguest plugin, which handles auto-updating the guest additions so that they match the VirtualBox version:
vagrant plugin install vagrant-vbguest
Now vagrant destroy -f && vagrant up:

Seems that VirtualBox and VBoxService disagree about what the active version is. A vagrant reload will fix that:

Now that's it's booted, let's check things out:
