My advice is to buy good properties in good locations even if you have to forgo cash flow.  

Obviously, I don't want my properties making people sick.

I know some regular conventional investment property loan programs have certain rules about this but does Fannie Mae?

We use it for managing our portfolio of SFRs and small multi's and it handles everything accounting wise for the properties so there's no need for quickbooks.You can also run your property management business expenses through Buildium or use Quickbooks if that's easier. 

I did a HELOC on my primary property to buy this one, which I rent and the cash flow is good.

- Should I purchase the property through an LLC for potential tax benefits?

Mixed-use zoning has been a goldmine for many of my clients, particularly those who started with owner-occupied properties and later transitioned them to full commercial use. 

As a teenager, I managed properties that I owned a percentage of.

Hi there, I have been looking into getting my first investment property.

What area is the property in?
