Hello, I am completely new to real estate investing and was hoping to find out from people who have been in the game for a while what a realistic earning potential would be from accumulating long term rentals over time. 

More rate cuts coming.

For now all you are going to see is more of the same because the vast majority of inventory is being held by people with 4-sub 4 rates and they can't/won't want to afford elevated prices and 6+ rates.

@Natasha Rooney rates will also be different depending on if you have Credit or not.

You can earn more by keeping your money invested in the market and letting your tenants pay off your mortgages. 

Rates are supposed to go down. 

And if the fed rate continues to drop, so will the mortgage rate. 

Hello @Jordan Wisser,I agree with you regarding competition heating up if/when rates drop.

Does anyone know a standard vacancy rate for San Diego? 

The property is classified as a B/C type of property, with the intention to implement a value-add strategy and it's going at a 6.5% cap rate.
