I have $80k liquid in CDs and savings accounts in the bank and a credit score between 760 - 780.

When you transfer retirement funds into a self directed account you can certainly buy real estate with it. 

Forced appreciation, where you do things to raise the value, should be taken account of in your underwriting.

Make sure you have enough saved up not only for the down payment but also closing cost, plus some reserve in bank accounts or in other investment accounts!

If it says on the website they pay $1,500 for X number of bedrooms, they probably pay closer to $1,150 once they account for the utilities.

If entities are disregarded, you can keep up with more than 1 in a single QBO account using the location/business feature to keep track of them separately.

With historical inflation in mind, that mortgage is essentially an asset.

Interest payments hit my account as expected.

Mostly on trade accounts with local businesses for the materials, some business credit cards, some of the contractors were OK with waiting 30 days for payment.
