Still not going anywhere yet, not even an estimated number.

I estimate my equity increase was between $30k-$50k immediately based on similar comps. 

I look at actual rental comps, and not some estimate from Zillow or Rentometer.

There also many unknowns like the actual inflation rate, an estimate is necessary. 

Also estimated rent?

DO you have a loan estimate?

I use to estimate you need 50 percent equity to break even, now I would expect significantly more.
