If it was the only land with right-of-way access I'd probably just offer the owners some cash to pay for that little section of land, however there's another lot adjacent to the one I'm looking at that also shares the same access.

last year i mailed a letter to the owners of record of a vacant home in Florida  I got a call back.

After he vacated, his landlord sold it, and the new owner flipped it. 

Assuming that is the issue the owner or PM can resort to cancelling the lease with 30 days notice. 

One inherited tenant actually shared that she was often late with rent because she just forgot - until the prior owner called.

The the owner has a redemption period and may still get it back. 

PENFED offers non owner occupied HELOC.

Now on to the post, I came across what appears to be a good deal, it's a packaged deal of six duplexes (owner will only sell as a package) that is being offered at $145,000.

Been there a lot of years and high points from previous owner. 

I’m buying a property subject to the existing loan and would like to refinance it in 6 months to cash out the owner and pay off the current mortgage. ( because i know i can get a lower interest rate than what he’s paying) How would I go about doing that?
