Hi Daniel,
I want to make sure you understand I have not done this recently. I would purchase an apartment building as a limited partnership where I was the general partner and signator. If the loan was assumable, I would assume it. If it was not assumable, we would do a subject to or wrap around loan and I would sign.
In some instances, there was already a first mortgage to an institutional lender, and a second mortgage to an additional company or previous seller. Both loans would be assumed or taken subject to.
Example:
I purchased a property in Colorado Springs by the name of the Bella Vista Apartments. It was 202 units. I don't remember the exact price (It was 40 years ago) but let's assume it was $4 million. I remember there was a first mortgage and a second mortgage. I need to make another assumption here as far as loan numbers. $2,500,000 on the first mortgage and $500,000 on the second mortgage for a total of $3 million in financing. The buyers would need to come in with $1 million or 25% down of which I would receive a 6% commission which was approximately $250,000. It was easier for me to raise $750,000 of the down payment and take a third mortgage for the $250,000 commission I was owed. As I stated in my book, I really didn't care whether I got cash or monthly income. It was all spendable! Times and rules constantly change in real estate and I only explained in my book what I did, not what is possible and legal today. I would be more than happy to answer other questions if you have them.
