If I end up filing for a tax deed in 2 -3 years and owning the lot (valued at $180K), can I force the MH  owner to sell it to me or move it within a short time period (10 days, 30 days, etc)?

I know there are a ton of factors but I was thinking this:Run the numbers on my currently owned property, and maybe see how much cash and equity it would produce in 5, 10, 20 years.  

Should I just file as a Sole Proprietor until I get a few deals under my belt?  

The woman who had the deed transferred in her name is only the court appointed administrator of the estate, from my current research she should be able to transfer deed but i will run a title search.She has been sending her lawyer to the courts avoiding being foreclosed on because the original note was not recorded correctly and they cannot produce it.

Obviously, it depends on the cashflow, that the property will produce.

I quickly realized that, if played correctly, the real estate platform could provide a solid foundation of wealth for many generations to come, while simultaneously producing cash flow today and allowing me to retire early.

You should allow them to terminate the lease without penalty....that is unless you want them to file a complaint with the housing authority, or the courts or some other entity.  

You may have to pay something for it, but it isn't a large amount.The only cautionary note is that some community owners, including myself, go to considerable lengths to avoid appearing in those documents so not every file is going to list all of the actual human owners.
