You will not even know if whoever you hire will do the job correctly in the first place because you yourself do not know what is the correct and proper method of construction and you are not familiar with the materials available to accomplish the job. 

Sean Terry interviewed him on his podcast #64, a very thorough discussion of his method which revolves around marketing to landlords  (a very saturated group nowadays).Anson Young talks about it in his bp podcast and Rob Swanson has a course on it that I haven't seen but he's interviewed by JP Moses on Moses' website. 

At this point, you ARE the junior lien holder so, whatever method you need to employ to get them to give you the payoff should be fine.

@Rick HarmonYour method of determination for pursing a lead is right on!

Adrian Smude I do have a question on your method.

Does your method of investing fit into your market.

I'm a young investor, and purchased a property via the "house-hacking" method back in November of 2014.  

I rented each room with weekly payment method, personally I like cash best.

If you do a little bit of searching on the BP site, you can find some examples of how to word the letter, or the general tone you should try with your message.Listen to the podcasts, there are quite a few about marketing and how to talk to sellers who might be motivated.I would caution against rushing anything, but certainly get used to doing "homework" on properties of interest that you find.The method you are describing is called driving-for-dollars, so do a search for that to see how other people have approached this method and what they say has worked best for them.Good luck in your research!

Use the methods you described and you will find something that makes sense.
