After several years investing as an accredited investor, I’m moving to building my own portfolio of SFH and small multi-family that I control and add tax and passive income benefits for additional investing.

I need help walking through the potential tax implications of those sales.

However, as the title states, it needs to be redeemed from back taxes, roughly 10k. 

The outcome probably depends on the wording of your lease and any related paperwork.Example: Thank you tenant for your $X payment for your first and last months of the lease.If the lease is otherwise silent regarding the last month, the tenant bought a month of tenancy regardless of future pricing.

Tax implications are never based on local laws because we are talking about FEDERAL taxes.

So transferring properties with existing mortgages into an LLC without selling them to the LLC is a common strategy for most real estate investors seeking to protect personal assets and possibly enjoy certain tax benefits.

And are there any tax implications from removing myself from the deed now?

I am literally in a sticky situation with the seller because she owes some back taxes on her property.

Whether the lender allows it will depend on the ratio required.

It would depend on laws in your municipality, but if you are going to allow pets in your unit, here are a few thoughts: are you going to have a size/weight restriction, and possibly a restriction on breed type?
