So productive that I’m looking to assist a couple getting their liquidation business up and running in our new location.

So if you do want a HELOC get it before you move out.HELOC - Pros: Fast cash, easy access, flexible; Cons: Floating rates or higher rates, less available equity as cash, short AMMO; use to take advantage of opportunities quickly then find long-term financing later, best to pay of quickly due to increased expense over other financing optionsCash Out Refi Mortgage - Pros: Excellent terms (low INT, long AMMO, higher LTV=more cash), stable/low INT rates; Con: SLOOOWWW to take out compared to HELOC, slower to reorganize/restructure or close out; generally these are good for financing other deals that are longer term and stabilized in nature. 

Though this is a pretty specific example, things of this nature are good to research to plan what areas will likely have rental rate growth which would lead to a more valuable apartment complex.I hope this helps!

Financing - If you are using financing for the purchase it will not be a conventional product.

From the month of July to August, new listings  in the New Orleans metro area are on a decline from about 6,156 down to 5,903.Do you think is because of the recent hurricane Ida, or is the market just naturally coming down due to the time of year.

This is the concrete product cast  on the upper floors of apartments.
