They will just wait for you to cancel the contract and offer on the listing themselves. 

To pay for this, I used a heloc on my current home.

The house has been on the market for many months..."

What's your thoughts on using Rent Manager for an investor that already has professional property management?

White Oak color and Walnut color are the two main ones you want to focus on, depending on the rest of the design in the house!

I would focus on REALLY GOOD Realtor. 

can you store dumpsters on site?

G'Day Alejandro,As a few have already mentioned, take a peak at Toledo also.In my opinion lower potential for long term appreciation but solid/"boring" cashflow.I prefer my portfolio to be "boring" but cashflowing lolLow entry points (Sub $100,000), high rents (Above the 1% rule).Blue collar working class decent folks that will stay and pay.Depending on the area but no derelict homes, yards well kept, cars with wheels and all tenants are employed.Plus, all are sophisticated enough to pay rent online so property management doesn't have to collect rents with bullet proof vests and shot guns lolI'm bias toward Toledo but it's worth considering.Wishing you much success

Baffling what "paperwork" they think they need to be on.

While you work on that, you could also explore creative financing options like DSCR loans or partnerships to fast-track your first STR.
