For the actual transaction + rehab I will need to borrow funds. 

Sometimes in makes sense just to cross collateralize the property to leverage your equity for use on another deal.

My best recommendation is to make your license active only if you are going to do several transactions, either for yourself or for a client.

I'm cross posting here and hope someone can offer insights –A property in my neighborhood came up for auction on the city’s listing.

Does this vary from transaction to transaction?

I have an excel sheet with each of our transactions associated with the rental. 

I may definitely look into hiring a real estate agent if the price is right and this may be questions better for the agent but I'd like to have a lot of knowledge before I even cross that bridge.

I am looking to inject (contribute) some money into one of my LLC to finance some new acquisition this year.I am refinancing my home (that is under my own name) and will use the cash out as contribution into the LLC.It is my understanding that while you can't deduct new mortgage or refi anymore on your personal home, you can still deduct all its costs when it is used for investment (by deducting from the investment income/gain).What would be the proper way to document this transaction in addition to the schedule recording the contribution in the LLC book?

In this case I think a business transaction attorney would be best. 

However, what keeps me thinking is when I find the motivated seller/ deal  and the motivated buyer - The part of the paperwork and transaction.
