Not really sure how to enter this area of conversation with the people who have already reached out. 

In renting this property, I've been able to amass a nice database of potential renters in the area. 

This would be a 100% refund for the unspent 4 nights, according to the payout adjustment.

Any other requirements on the seller to do this correctly ?  

This amount aligns closely with your rental income after expenses, so you’d be cash-flow neutral or slightly positive.At the end of the five-year term, you could aim for a balloon payment based on the property’s future value, which should appreciate by around 4% annually.

In this last year, their communication with me has become almost silent. 

@Liliana Galayou will need some of your own cash - there is no way around it and borrowing 100% is high risk.also - not to discourage you, but to help you - flips are tougher than as portrayed on HGTV. 

HELOC at 75% LTV will give me access to $155k, but the rate is around 8-10% and is subject to going higher, considering the current instability with inflation.

I heard rumors of the insured people from the Marshall Fire a few years ago were under insured at around $250 a square foot and can't rebuild. 

This is a great place to learn and to connect with people so take advantage of all the great resources.
