We tried searching on Zillow and other websites (e.g. rate-my-agent), but seems like the result is not coherent.

How long can you do that to achieve your results?

I'm getting good results for our clients with postcards and some paid ads, but I'm looking at implementing cold email and cold calling as well.Any good companies to buy lists from?

But I got really frustrated with developer who was unresponsive and lazy, unable to deliver quality results on timely schedule as agreed, so I fired her and decided to try Grumpyhare.com.

@Brett Deas  The issue with furnished finder we have is the radius of the searches and the data it pulls in for stats as well as matches for the property. 

There is an alternative that involves doing cost segregation on property you purchase and using this to help offset cap gains resulting from failed 1031 Exchange.

This was last week and I am still waiting on the results.

And then to be scolded over how I "mishandled" my mortgage for 4 years during covid-19 and resulting other medical issues, which now looking at it, seems as if it was meant to shame and guilt me into thinking I had no other option. 

It heavily effected his under writing results.  

Not brainiac stuff here, but in the end, it's the simple-but-tedious work that gets the best results.
