Hi,
The hardware side is straightforward, but the software side of the system you want is a tremendous amount of work and potentially bug prone. I'd recommend using an off the shelf solution if possible, given the edge cases for such an implementation result in either unauthorized access or legitimate access blocked.
To start, what you want is probably 13.56MHz RFID. It's close range and used for most card reader systems and keyfobs. The reading distance is generally determined by the power in the reader antenna. There is no power source in the RFID chip itself, so it activates as soon as any part of the the chip's mini antenna gets in range of the reader.
That said, you are intent on the DIY route, here is how I might build such a system:
1x Local network authentication server.
There are many moving parts on the software side. This could be months of work for a single person depending on the requirements and how much time they spent on it.
RFID Reader (per door)
This is what a Mifare looks like attached to an Arduino. The breadboard is only involved for testing so I didn't have to solder the mifare. Was still testing different configurations.

Advice
Part wise the above is cheap, but implementation is really time consuming. It also does not address actually opening the doors. I'm assuming you have electronic locks. Factoring in time to build and test I would probably go with something like this (quick google search, sponsored result): http://www.maglocks.com/rf-m8500-mortise-rfid-card-hotel-lock-with-built-in-deadbolt-by-digi-electronics-for-209.html. Surely not the best on the market but if I found one in 30 seconds, I'm sure there's one out there specifically for your purposes.
Homelink should be pretty straightforward, assuming that the code is fixed and not rolling (in which case you would probably need access to the "learn"/"programming" button on the main controller).

RFID cloning is a little trickier. If the complex is using 125khz prox, this is probably your best option:

​
It's a relatively new product aimed at pretty much your exact use scenario. I've had good luck with it on 125khz, but if the complex is using a more advanced (13.56mhz) system, you will need something like the Proxmark3 and a good bit of time to figure out how to use it.
I got the ring 3D model here
I got the tags from here
I dropped the tag in acetone, and let it sit for a couple hours. After I pulled it out, I re-wrapped the coil tighter and superglued it to the ring. Then I put some black electrical tape around the chip for added protection.
It actually works pretty well, but the range was shortened quite a bit.

Here's the link to the on Amazon
What is important is the Card. The Standard you Need is NFC Forum Tag Type 5. Based on ISO 15693 Standard. You will probably have to make your own antenna for a reader that supports read of ISO 15693 cards.
Two Chips support the Standard. The NXP iCode SLIX and the STMicroelectronics ST25TV series. The only thing is that there are several out there but a lot is based on the Antenna in the tag. Several do not mention distance obtainable.
rfidcard.com offer type 5 cards. https://www.rfidcard.com/product-category/nfc-card/nfc-tag-type-5/ But they sell bulk. Plus all their NXP SLIX cards all list up to 1.5 Meters but their ST25TV cards both say read at 10cm.
​
Now Yarongtech has Icode Slick 2 Cards but they do not list distance. This card has the right chip and ISO it will just take some experimenting to see if it realizes it's full distance.

The hardest part is finding a reader that will read ISO 15693 Type 5 cards and has enough power to do it at the full distance.
This is probably too much work for a single small client... just throwing it out there. Something like this works with lots of (but not all) smartphones:
http://www.amazon.com/RFID-ME-Android-Powered-Devices/dp/B007KXC1NO
There's an Android app with source code available that shows how the basic reading/writing works:
https://github.com/mti-rfid/RFID_ME_GUI_APP
(I have this setup, and it works fine close to the tags.)
It doesn't sound like you need much range, so barcodes and NFC tags might be good options too...
Something like https://www.amazon.com/Ceramic-Eclipse-NFC-Ring-Programmable/dp/B01B2319OY/ assuming the door readers work with NFC.
