As of last night (Thursday), I now have a signed lease with a paid security deposit ($1350) and June's rent ($1350).

The security of fannie is what allows for such a low (25%) amount of equity. future investment properties will continue to fall in this 25% bracket I think you can buy a higher rate and do 20% down for the first few, but with rates rising that won't be as lucrative anymore.

you may want to blend your portfolio or cash.some depreciable assets ( rentals)syndications  with a VERY good Vetted SponsorPerforming Trust Deeds  Be the bank NPN  funds  let the operator do all the heavy lifting in that space.stock market then see what performs and what you like.. 

Looking for any input or suggestions that would allow me to secure this deal quickly.  

Even if you find the right deal, securing the right type of funding can be a pain.

Some loans are secured, while others are not.

When we had performed a walk-through of the property, the tenants had covered all the smoke detectors to smoke pot in the house. #2: we like that unit the best and plan to live there for a long time. #3: we like the other tenants and want to keep them.

The HELOC is secured by your personal house, the new loan likely the property.  

Go to an area that is performing well and near your living place at first. 

Her advice, candor, helpfulness, and willingness to do what it took to secure me the best possible outcome was incredible.
