I actually enjoy visiting there from time to time. 

This would further support the recommendation to negotiate a step-down mortgage structure, such as tiered payments or interest rates, to reconcile the seller's valuation expectations with the practical realities of the park’s financial performance and provide a feasible acquisition pathway.

We'd all love to do deals at 40% DTI with 5% down all day long, but that's just not reality.

It's easy to cheerlead and harder to actually DO the work.

It looks like "Good Egg" is simply an Entity that collates funds, and then invests those funds on your behalf with the actual sponsors/general partners that actually purchase the properties, get the loans, manage the properties and distribute the funds.

Actually have people contacting me before I advertise a unit available.

This is just expected, would think if it did not happen it's actually bearish news.

One would think that a bidder would pay $45,000 in my example (since they are assuming the first mortgage), but they are actually bidding $225,000.

The more traditional way, assuming you actually have adequate equity in your rental, is to take out a HELOC on the rental. 

So, you didn't actually close with them?
