My idea is that the 5 of us would save individually and all pool our cash into a sizable deposit.

I write my leases stating which party is the one to receive a refunds of the deposit.

In the future, ask for deposit as earnest money.

I have application with clean background checks and credit score of around 680Income to rent ratio is 2.5.I have asked for a consigner.However I am wondering if There are any other options worth pursuing to mitigate the risk - such as ask for 3 months rent as deposit instead of one month ?

Some tenants need that deposit to put down on the next apt. as they don't earn enough to come up with another 1st, last, and security.

The landlord is asking for $2,800 as a security deposit.  

So long as the $10k deposit was done 90 days in advance, should be in the clear.

The Tenant/Buyer puts down a deposit (which is usually your fee) and signs a lease and option agreement (separately) with the seller.
