Can't you get pre-approved by a lender then use that letter as proof of funds when making offers?

Does anyone know how I would go about making this work or any HML that would provide PROOF OF FUNDS available in my name so I am able to make CASH offers on these houses??

I won the bid, seller accepted offer, earnest money wired, contract signed by buyer and seller, proof of funds accepted.

Some only want 2 years experience in general and will count it like Lynn said above (proof of signed lease and income being generated) If you plan on staying with one bank for a while you will want to ask this question before obtaining your first loan with them.

Also the agent said they usually require proof of funds!

The probate attorney should vet YOUR capacity to purchase and want a bank statement from you, a lenders pre-approval, or a proof of funds from someone such as a transactional funder. 

Find a money partner or a hard-money lender who will give you some type of proof of funds letter, or a bank that will give you a pre-approval letter.  

I have seen a lot of posts on the subject of Proof of Funds Letters and I still have a question:  Are there certain companies that provide Proof of Funds Letters that are kind of placed on a black list, therefore negating the viability of the deal before it is even started?

The bank will want some proof of funds before they accept an offer. 

If they could actually show proof and ability to purchase if the end buyer didn't come through that would be different.This reminds me of another situation years ago I heard about where brokers/agents would offer to "buy your house" if they listed and it didn't sell in XX number of days.
