We had the same thing finding a broker for a /24 pi in the RIPE region. Not all of the brokers have the size you want, eg a /20 when you need a /24.
It ends up being between 2500 to 4000 euros depending on notary fees and if you already have a LIR agreement.

Where is one of these v4 markets that we can buy some IPv4 space from?
I would prefer to have a place where we could see recent transactions, something along the lines of x amount of addresses for y amount of monies.
Google search is failing me for some reason..

Should we enter them all into Yelp and start rating? That's too many to
comparison shop. I'm being a little wry, I know who is naughty and nice.
I've been tracking them all since the beginning. Not everyone else has. The
potential for harm to network operators is moderate IMHO.

Thes folks (and I am not advertising or affiliated with them) publish a list of most recent transfer completed:

http://ipv4marketgroup.com/broker-services/buy/ vs.
http://www.ipv4auctions.com/previous_auctions/
If you compare the pricing that both have made available you will find one
is posting average prices exponentially higher than the other. When you
trend the granular auction site data the auction numbers demonstrate a
trend would expect, that smaller prefixes are more expensive since it
takes a similar amount of effort to process a /24 as it does a /20. Dollar
differences between a /24 unit and a /17 unit move the needle
significantly.
Based on both of both sets of public data its easy to conclude that
auctions will work for at least small buyers of space if they're
sophisticated enough to address the RIR issues. If you do decide to take
the simple broker approach (not all are simple and not all approaches are
suitable to simple brokers), use an RFP. And Yelp.

Hello, folks!
I have finished multiple (and 5th in RIPE) inter RIR subnet moves in RIPE
region. We have moved multiple /21-/20 networks and awerage cost was about
$10 per ip.
Price varies significantly by prefix length, and somewhat by region.
Regional variance may not be as much as it used to be.

Does legacy space command a premium in this?
What's the going rate to lease space (say a /20 or /19 for discussion)?

From what I understand, and I have not been a party to any transactions,
there are differences in transaction where the space looks ³cleaner.² That
is, space that has been less delegated, and has never appeared an a spam
blacklist. I don¹t know whether that translates to higher prices, or
whether buyers just won¹t buy questionable space.
What's the going rate to lease space (say a /20 or /19 for discussion)?
Leases aren¹t worth the trouble, because sellers believe that the only
reason for a temporary lease is to originate spam, following which the
address space is worthless. So if you can find a lease at all, it is
likely to cost as much or more than buying outright. Personally, I
wouldn¹t lease space at all, because I wouldn¹t want my organization¹s
name anywhere near it when the bad stuff started happening.
The ipv4auctions.com site lists prefixes that large; recent /20s have been
$7.45-$8.00 per address.
Bear in mind that I¹m essentially a researcher, and have no direct
experience. You might want to talk to a broker or three.
