It sounds like you are rocking on all cylinders and moving quickly towards building a sizable net worth.It also sounds like you have a systematic philosophy of building up capital, taking advantage of your current opportunities, and are on track to buy more property.

So new roof totally lead free meaning new door frames etc new kitchen two new bathrooms and sheet rocked the whole house redid or carpeted every inch of floor.

Your ADU already exists and the property is zoned for more than one unit - why rock the boat?

@David Vile"The question is, is it legal for our "A LLC" to purchase the property from the other "B LLC""Yes, however "what are the tax ramifications" is a separate and important question.If your partner owns more than 50% of both LLC A and LLC B, and the property has an unrealized loss, a sale between the partnerships can get a little tricky from a tax perspective.Regardless of the previous sentence, there may be a planning opportunity here depending on whether the property has unrealized gain or unrealized loss. 

I live in the area on Cecil B and frequently walk past the house.

Rock the boat at your own risk.

There is a difference between B- and B+, and it's sort of a 'you know it when you see it' situation.

If they are at market rent and paying even if it’s late I would not rock the boat too much.

Does anyone have any recommendations on a place to purchase poly rocking chairs at a good price?

I've been scouring Zillow and noticed the rock bottom prices due to $75k equity membership.
