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. 

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?

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

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.

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. 

The rate and points will also be highly sensitive to the LTV, credit score, DSC ratio, loan purpose, loan size, and property type. 

Probably go for that sweet spot in between.An architect is probably your best bet at this stage.

A thousand gallon tank, which would be about the size of a small-to-average septic tank, with a cabin with 2-4 people staying, is likely going to fill up in less than a week unless they've piped the grey water (washer, shower, kitchen sink) somewhere else like a dry well.
