Quote from @William Fuller: When deciding to potentially acquire a piece of land that a wholesaler has under contract, what information do you need about the land or parcel?

Bigger projects (more than 150 units) have a 90-day eligibility review and a 180-day final approval deadline.

That 4% cap rate on in place financials is a lie.  

I had a rental house that burned down. 

I plan to utilize some cash, margin loan, 401k loan, and a HELOC as a down payment.My first house hack (now an out of state investment) has a Zestimate of $530K, and I have $266K left on the loan.

For almost $100k a lot you want a pretty high NOI to make sense of it, like over $300k IMO I agree.

Since you already have experience with both short-term and long-term rentals, house hacking a duplex could be a smart next move.

You don't always have to incentivize a tenant with a discount to get the tenant to stay, nor keep rents stagnant, but it is good to be aware of the business impact with respect to cost too.

Fear of a recession etc.

You are definitely going to want to get a lawyer and as soon as possible.This will sound harsh.In your story, you have made a number of very poor decisions about how you purchased and managed this property.
