Hi Anthony!
I will drop my two cents here, but please keep in mind this is just knowledge as I do not have any rentals of my own, Im saving and searching for my market.
That being said! If I were in your position I would definetly go with more units and less rent.
Why?
We have been in an amazing bull market run. Credit worthiness is everywhere... but as Benjamin graham says the higher they rise the harder they fall. It is not a matter of IF, it is a matter of WHEN, and that nobody knows, which is why we as investors buy right. The market will correct it self, and the first properties to go vacant will be the high end rentals. Middle class Rick will realize he can move in with his pal into a smaller unit and save 3/4 of his money. Grant Cardone says money doesn't go away, it just shifts. Grant him self doesn't buy A+ Multifamily.
Also buying a multifamily with lower rents raises the possibility of value add. and that is more beneficially to you because that can create more equity in the long run.
I hope this helps!
