Mortgage is at 3.375% 30-year-fixed so cash-out re-fi before renting it out might not be sensible.My family now needs more space and am considering buying a SFH in the ~$1.5m range. 

Many commercial loans have clauses that state that the bank has final approval rights for any major lease in the space (the square footage is usually stated in these clauses). 

I got the master with the attached bathroom and both garage spaces. 

I'm in the MFR space where I own and manage my apartments, so if you ever need any help analyzing any deals, I've built a financial model that would definitely help avoid some problem properties.

I have others with funky layouts, like no counter space between the stove and fridge.

The lending in this space is becoming more mature.

Little bit more space and get to keep some animals. 

Framing is done and we are looking forward to leasing the space.

They will only ever be allowed 18 lots on that property because the DEP deemed the flat space below the park to be wetland.

All of the data is shown right in front of you, and you have to apply your own heuristics for selecting the appropriate comps including their age, distance from the subject, counts of rooms, size within of each other, lot sizes, etc.We can discuss all day long about how good or bad Zillow data is, and honestly, it depends very much on the market, and how quickly a sale gets reflected in the public record.In my SoCal market, it's actually pretty quickly, and I often end up using a blend of suggested comps from Zillow and my own comps that I import from other places such as Redfin, your free MLS alternative.
