The property is a cheap 4-plex in a college town near us that is already fully rented, and the rental income surpasses the PITI, but that’s where we run into my question.

I worked in casinos dealing cards, while I don't have any type of security or police type background I grew some thick skin.

It paid off the existing loan and left me enough money to fully fund the purchase of a 6 plex in Oakland Ca. 

I don't think the duplex would be considered multi-fam, whereas a 4 plex is? 

If it is a 7 plex, then you should be able to do it fairly easily with Excel.

There is a reason Wall Street investors buy single-family homes. 3 single family homes in the same area is essentially the same as a tri-plex. 

There are 6 air bnbs (3 duplex) they are building using the money from selling 12 SFH in the deal. the deal includes this and a 16 plex. 

I was looking at 4-plexes in Georgetown and saw that there were apartment buildings nearby recently renovated, pools, gyms, and other amazing amenities.

Wondering if anyone has ever weighed the pros & cons of adding an additional unit to a 4-plex?

However there are some reputable new construction builders in the area.There is, as you likely know, a housing shortage and, once Caesars Casino opens at the end of 2024, they anticipate 2 million visitors a year.
