Take a semi-retirement and get a gig that is a more chill when you come back. 

I am the executor of the estate and my brothers agreed to let me buy them out on the house so i can use it as a rental property to supplement my retirement.

Both brothers were retiring, and one was in very poor health.

We are also new to investing but looking to jump all in to fund our retirement.

My replacement CPA retired after I requested he file my extensions.

And yet people put funds (often 100% of their retirement funds) in to IRAs and 401ks for 40 years with zero cash flow.

Hi everyone,I’m new here and recently connected with someone looking to retire and sell his portfolio of 19 properties (a mix of multi-family and single-family homes).

Since you are looking for passive income from a rental to aid in your income once you hit FIRE & retire, I'd focus on building a portfolio that begins to build on that cash flow to replace your W-2 salary. 

It defers taxes and lets you get into a more stable property.

Consider factors like retirement, landlord fatigue, property maintenance issues, or asset liquidation.
