I've done a little exploration on the free AirDNA and it looks like there's potential to take in a significant amount of money from very modest sized properties.

Because I am starting out, I have been self-funding my "gap," which limits the size and scope of the projects I can take on.

That also means that if you had to break contract because of it, you would be in breach, and would forfeit your earnest money.We, as an example, have letters from both our banker and one of our HML (that we use depending on deal size) that states that we do in fact have immediate access to "x" dollars.

We don't have any apartments any more, but when we did manage them pets were strictly limited by size and type.

No one size fits all on the journey to independence.

If it's just you or just you and a partner, your best bet when looking to house hack a multifamily is to look for uneven unit sizes.

Likely because of the credit card processing fees, size of purchase, and the the risk of chargeback.

A market is defined by common properties, of the same size and type, within a specific area. 

What sized land can you buy.

The biggest is going to be whether the HVAC is properly sized for the building.
