Could you go reinvest it in another property to build even more income?

Meaning you can sell an apartment and purchase an office building and it's a valid exchange. 

It is one of the reasons rent by room is more difficult to manage.I have no experience with rent by room and the associated common space.  

Hello Evan, I have helped a number of Bigger Pockets investors build their portfolios in Syracuse and surrounding areas.

A cost segregation study was performed on this apartment building in Knoxville, TN with a depreciable cost basis of $17,323,250.

I have a 12-unit building and after going through a lot of leak checks, my PM and I have come to the conclusion that a tenant or tenants are wasting water - to the tune of 5,000 gallons a day (a normal day is around 800). 

A good manager will handle tenant communication, security deposit transfers, and ensure a smooth transition for you.Changing managers doesn’t have to be difficult—following the agreement and partnering with a competent new PM will help you get things back on track.

If you want to be generating leads from a website, SEO will help with credibility and long term visibility, and an attractive website will also help with building credibility and trust too.

I would second out near Heber since they’re building the new world class ski resort out there soon.

- Renting it Out: The likely rent I'd get in this area will cover half my mortgage payments at the moment- Add Square Footage: Taxes will likely go up significantly- Build an ADU: Overall ROI will likely not offset much since it'll still be counted as value tied to the one house- Selling Off Land: Sits on .5 acre that I might be able to sell.
