Are you signing all documents, contracts and agreements with your corporate title?

Those two alone are a minimum of 60 days (I would think).

A lot of questions here...As your dad has a 50% interest, and a trust owns the other 50% of which you and your two siblings are the sole beneficiaries (I presume), it might be advisable to, after the trust interest is distributed, to have your father, you, and your siblings contribute your interests to an LLC in exchange for shares of the LLC (usually called "units").The property would be re-titled in the name of the LLC and the LLC can use it as collateral for a loan.It's usually highly advisable to engage an attorney to draft an operating agreement in this scenario to get everyone on the same page about ownership interest, who is/are the managing member(s), what happens when someone wants to sell -- do the existing members get 'right of first refusal', what happens if a member passes away, etc.

This rent to own agreement has gone terribly wrong.

However, mine isn't and requires a good bit of principal pay down included with the minimum monthly payment. 

It takes a minimum of 15 minutes to get to ANY freeway from my house, and the traffic here sucks because there's a light at EVERY intersection. 

Lastly they are willing to do a lease purchase agreement which is the most advantageous to both of the parties I do believe since I now have experience with this technique. 

A couple of times the buyer Insisted on seeing either an email or a signed counter offer from the seller.....that never went well, my clients never did the signed counter offer, but one sent an email telling them I was doing exactly what they wanted, and don’t bother them again.When and if you come to an agreement, then modify your offer accordingly, sign and submit.

Real estate prices here are super low so I would have to purchase a number of properties to hit the minimum loan amount for a number of lenders.

@Bryan Morgan, I can only assume they're insisting it be a joint account because both of your names are on the title/property-management agreement, which makes sense.Fax them over either an account statement with the account info and both your names or a letter from your bank.
