Moreover, the Deferred Sales Trust has greater flexibility than a conventional installment sale with respect to investment selection(allocation of stocks, bonds and mutual funds), risk management and the repayment timeframe.

Recently Fannie Mae changed their policy and allow the property to be in the name of an LLC if that LLC is owned by the same person as listed on the note.Commercial loans typically have more flexibility in the terms, but will come with a higher interest rate. 

This will give me more flexibility with the structure of the new loan for the Buyer.

Also, local lenders seem to be more flexible in doing deals than more regional or national banks.

Also, try you're local credit union, they're a lot more flexible when it comes to lending.Hope that helps!

Try a local commercial lender, they might be a little more flexible with their underwriting guidelines

Sounds normal to me.You are a flexible landlord, meaning you will work with your tenants.

This will allow you to get the max amount of cashflow you can upfront on the property, but also gives you the flexibility to pay the loan off as fast as you want. 

It gives you more flexibility.

However, I wouldn't want any new tenants feeling like there is wiggle room on how flexible I am with delinquent rent.
