Quote from @Erin Church:
When doing a little planning with our CPA, my family felt we needed around a dozen or so rentals to be comfortable. Our CPA insisted that we need at least 20 units to minimize risk. I'd love to hear how to safeguard against risk of non-paying tenants with the idea that pandemics/eviction moratoriums can happen.
Hi Erin, sounds like you've got a good team around you with a CPA who helps you do planning.
Although it can be nice to get a minimum number of units for a little diversity of income (5-10 units), I don't agree you need to keep growing to some set number (like 20) in order to reduce risk.
Instead, just have healthy cash reserves to get you through the cash flow ups and downs. In the end, you'll figure out the normal vacancy period for your houses.
For example, if it's vacant 5% of the time, you'll receive 95% of your rent on average over the long run. But some years you'll get 100% of the rent. And another year (when the tenant moves out), you may get 85%. A reserve can plug that 15% gap if you need it, and then you can refill the reserve once the property is full again.
Adding more properties adds its own risks, like more debt, more maintenance, more things to think/worry about. So, it's a balance which I try to help us all figure out in the book.
