BPrs that bought using owners 20% for down payment

[Mike Campbell]

Looking for info from BPrs that bought apartment building using owner financing 20%

Looking for the proper way to write offer asking owners to finance the 20% needed to buy apartment building.

Offer 1.3m, would like owner to finance 300k,( Actually 23%)at 8% interest only for 5 year balloon.

I Have never asked or done a deal this way, want to make sure I get it right the 1st time

Any suggestions or help of any kind would be greatly helpful.

Thanks

Mike
