Ok, so I had an extremely motivated seller approach me about buying their property.

This is not technically correct, but the most practical approach is ATM.

Some providers take the approach that a furnace or water heater with several years of expected life shouldn't be replaced in the rehab, but that the final product should be priced accordingly.

Would love to chat with you more about your approach.  

If approached correctly (hand picking those with the greatest potential for STR cash flow improvement + best current as-is cash flow), Sedona SFH's between $1M - $2M are yielding gross monthly income at approx. 1%-1.5% of purchase price + renovation, especially after reasonable improvements (Some are completely turn-key but have higher cost, some need $50k - $200k).And I agree with another post that in most areas, this is not attainable anymore.

So… I need to hear how you creative minds would approach this situation to maximize my equity. 

Not every, but enough times to wonder about his special abilities to read and profile people.I am also very good at doing door-to-door sales and I have a super simple approach.

The radius approach could include more than 1 neighborhood (especially if there is an "accross the highway" scenario), I have access to propstream, flipster, and others but none of these tools actually have neighborhood data what tools are you all using to get comps in the same neighborhood? 

That is probably how I would approach this dilemma. 

Depending on the style/approach for your str business.
