Only a handful of bookings, so she's needing to supplement with longer term tenants. 

In addition, supplementing my RE education with in person seminars definitely can't hurt (as long as they aren't $300 a pop).

You can also sell on contract, via a wrap note, using a note if you own free and clear, etc.I think the purest form of buy-and-hold investors generally intend to hold the property indefinitely to produce cash to supplement or replace their income.

Also firms and third party providers may interfere with the planning process.Regardless most people don't realize how much better off they could be because they don't have good guides to help the navigate the retirement land mines.An individual might have a lot of bond interest income supplemented by net rental income and find that 85% of their social security is taxable.

Also keep in mind that the cost of life insurance is going up every year and eventually premiums that you are paying are not enough to cover the cost of the insurance, at that time funds from your savings component are used to supplement the cost of insurance.

I don't know that I'd currently risk my credit score for $750 a month, but maybe when I'm done with acquisitions or I move purely into commercial it'd be a fun little supplement, enough to buy and maintain a little hobby boat or plane.

It's a good supplement to BP, books, etc in that networking locally is an important aspect of meeting the local players, forging potential partnerships, learning about opportunities, etc.  

A seller carried note, in this case, is an opportunity for her to supplement her retirement income.I'm going to sandbox here, obviously it's unlikely you will do exactly this, but it's a starting place:If you want to play the long game, and are yourself young enough to do so, you could pair the seller carried note with peppercorn rent specified in a lease of $1/mo that lasts until she dies.
