Mapping it out is easy using the lot size, sqft, bed/bath count, property type, local rents, and location.

OP what type and size of deals are you seeing flow? 

Under 18-20 months is usually a solid bet when you consider the hedging effect. 

Your best bet is between Yardi Voyager and AppFolio. 

Would QuickBooks be my best bet or is there something else that would fit my needs better?  

Inventory is tight, and new construction is gaining traction. We’re building financing models to support both paths. Which side are you leaning toward and why?

I would say 99.9% of these calls /emails go ignored because they come across as spamIf you do not have a specific message with a way you can assist them and an opportunity that has already been fully vetted with all the numbers then it’s a waste of our time.Your best bet is to go to conferences, and prior to the conference check out who is attending and set up some meetings at the conference in advance to meet them in person.

Along with that you need to keep risk low/moderate (don't bet the farm with a family). 

You can speak with an attorney to see if its a buyer beware state or if it had to be disclosed as well as if you are within the statute of limitations, but my guess is gonna be you are not going to get very far attempting to sue as a size of septic is something that can be verified by public record in a search. 

TLDR;By my findings, if you are a long term Airbnb host/Superhost, etc and had your bookings DROP OFF A CLIFF this summer, switch to "Flexible" cancellations and I bet your bookings will go back to "normal".So I have been hosting since 2018hundreds of reviews, still over a 4.9+ score.
