For annuities sometimes you can spread them over several years even if you inherit them. 

I'm thinking this type of investing would be perfect for people I know with $500k+ sitting in equity or low-yield annuities.

RMs are annuities based on the value of the home and age of the borrowers.

These are nothing but annuities and you take any slice you like.

Is there a way to leverage the funds I have in my 401(k) and annuities to acquire hard money?

The ONLY "guaranteed" returns are bank CD's, bank savings accounts, government bonds, and annuities.

I would put 100K into a 10 yr. annuity and use 80K as a down payment for a couple 150k to 200K homes and keep the 20K for emergency funds for your properties.With the rule of 72 you'll probably have 200K at the end of 10 years and you can repeat.  

I only say this to inform you I will never waste anyone's time and I am not on here to be the one of the ones "who fail or don't make it" like question 3 in the fire round.My beliefs on money, savings, and being frugal allowed me to aquire a savings of $75,000 while having an employer paid annuity and just purchasing my first single family live in home.

For example using bonds assigned as additional collateral or structuring a deal to save the seller taxes thereby giving a better price or terms.While writing this I got a call about someone wanting to sell payments that are received from a court order and my suggestion was not to deal with the scum bag but to loan the money to the payee and assign those payments as collateral with the right of offset, that puts the payee and payor on the hook instead of buying the annuity payments.

Can the carryback financing be pulled off where the buyer buys an annuity that will fulfill the financing promise to the seller?
