To get a rough ballpark, sure, but sometimes you'll be way, way off like we've seen with the iBuyers who it turns out were too smart for their own good and ended up buying high and selling low due to to relying on data and not actual organic, boots on the ground experience pulling accurate comps like an appraiser or realtor who knows the market on not just a block by block or street by street but a house by house level.

If you're willing to have roommates, your options open much more broadly, and you can potentially assume a loan with a low interest rate. 

Quote from @Jacob Sherman: What type of loan products are you in the market for ?  

Low property taxes (1.1%) and not a lot natural disasters as well.

For your part, it might seem like a free roll of the dice to go to court, but there are surprises and landmines along the way, litigation always takes far longer than anybody expects, and the time and emotional expense of fooling with litigation are energy drains on more productive endeavors.

Currently living in our home and plan on renting to keep low interest rate while we house hack a duplex to start our investing in real estate.  

Get a firm quote before committing.If appreciation is low, ensure rents are strong enough to justify the effort. 

You can still achieve it, but finding deals that actually pencil out on all criteria (low enough purchase price, low enough renovation cost, cash flows on the backend, all cash out at refinance) is pretty hard.

You can proceed with a cash out or rate and term refi up to 65-75% LTV depending what product and terms you choose.

There are also several funds out there that provide high single digit yields that are low risk.
