If you want to hear all the advantages of San Diego RE you can PM me but suffice to say it has historically produced very good returns and this is verifiable fact (anyone can verify this).However, you do not know whether you plan to stay in San Diego. 

First, you get bids and verify licenses.

Is there anything I should do or get from them to verify them as a company before moving forward?

I'm currently reading a couple commercial real estate books (one of which is a textbook) where the author speaks of some of their own experiences (for example, incorrectly verifying all owners of a MF he was trying to purchase thus being unable to sue for breach of contract when they backed out).  

This way you will be able to show the tax schedule to the lender to verify income. 

Currently he only needs funding to help cover the rehab completion.Here's a summary of the dealARV: $315k (I've verified that this is in the ballpark +/- 10k)Purchase Price: $130kRepairs to date: $32kAdd'l rehab estimate: $25k << my pieceProposed terms from my colleague:I am offering 13% annual on a 12 month note with a guarantee of minimum 10% return.

But you'll need to verify the requirements for that.Lots to know, right? 

*Update* I did not get the property The home inspection uncovered way too many big ticket issues.To verify U&O I visited http://www.baltimorehousing.org/permits I also called the city and verified that the property did not have a U&O and an expired water heater permit.

(Had to make special arrangements for them to accept a cashiers check with escrow acct info on check and got deposit slip from bank officer after verifying account with escrow company, I almost backed out of deal and it would have affected two other contingencies).I have other questions in regarding the escrow process which I found unprofessional .

@Edgar Perez trust, but verify.
