The seller discounted the price of house a bit but asked us to transfer the lease to us (they wouldn't take it with them).

However, my lawyer says there's a possibility of lingering inheritance tax since the property was transferred to a son in 2014 who then never paid the taxes.  

A question is what kind of reactions from the tenant when I inform my intention to transfer their home to an LLC?  

You can just have the title transferred to your name.

Transferwise only takes a very small fee to conduct the transfers and give you the actual mid market rate. 

I am confident I can sort it and figure out which person/LLC owns the most property.

You say you want to wholesale then most of those leads will be dead you need to know how long ago the property transferred to ensure they have some level of equity, you want to make sure your not mailing to vacant land or properties, wrong price ranges, and you want to be area specific.

Hi everyone, my Dad and I are trying to start investing in real state I have bad credit and will not qualify for any loans, my Dad has already paid off our home but he has a disability and will not qualify for any loans even if he uses the house as collateral; can I use a quitclaim deed to transfer ownership onto my name, and if so, can I apply for a home equity loan right away to buy another property once I acquire ownership?

It should specify how much money is being transferred, for what period, how the money is to be paid back (interest only, principal + interest), at what intervals (monthly, quarterly, annually), and whether pre-payment is allowed, etc.

It can take months for the property to be transferred to FNMA from the bank who owns the property.
