If you are looking for multifamily deals your time/money would probably be better spent taking all the major brokers out to lunch/coffee after touring a deal.
Relying on loopnet/crexi will not get you the best deals.
This is how the process works:
1. Seller gets several BOVs (broker opinion of value) and quotes from local brokers.
2. Seller chooses broker.
3. Before bringing the deal to market the broker floats the deal to known buyers and potential buyers they have a relationship with or have known deal criteria. This is their primarily list, the A list of buyers and the list any serious buyer needs to be on. They aren't sending these "off market" opportunities to people who are only looking online. The brokers like this step because they don't have to spend time and money on marketing, tours, etc.
4. If they can't hit the whisper or strike price it is then marketed first to those on the brokers email list. Tours are scheduled, offer dates are usually set. This is the secondary list.
5. Some brokers will at the same time list on loopnet/crexi, others will wait a few weeks before putting it on any online list, or they will wait and see if how much traction comes from their primary and secondary lists. If there's little traction they will throw it out to the general public.
There isn't a ton on the market right now, so buying better access to loopnet really isn't going to increase deal flow in a material way. Networking with brokers to get on the primary list should be the goal - at least the secondary list.
You often have to close a deal with the broker to get on that primary list, so at least shoot for being on the secondary list.
We have the national co-star subscription, it's expensive (like $40k/yr), but we're also trying to take down $100-200M in multifamily this year and need the best data in order to make good/quick decisions and not to rely on brokers for everything.
