@Jerry Padilla or @Upen Patel might be able to guide you here.

I would suggest looking at some of the free guides under the education tab above.I would learn ans much as you can from this gentleman but I do see a conflict of interest in that he is trying to sell you a property and yet one of the most important things to learn is how to evaluate a deal.

Of course, you need to read The Ultimate Beginners Guide to REI here on BPIf you haven’t already, please read/listen to these books ASAP!

If you cannot walk into your local bank and credit union and based on your relationship with the bank IE large deposits and I am talking in the multi hundreds of thousands.. or very large incomes I am talking in the multi hundreds of thousands.. and or very long experience level I am talking decades there is NO money at those rates. what there is   is money at 9 to 15% or higher.. once you grasped that concept and folks stop wasting time.. then you just plug those numbers into your deals.Now if your talking about yoru 4 mortgage slots for rentals  that's a whole nother story but if your looking for fix and flip type funding  etc etc.. the niche is the HML in the country and there are a lot of themget a copy of the Scottsman guide there are list there of reputable national HML.

It shouldn't take long and learning how that works is valuable too.

I am running into that same issue but did find the user guide for the data file on the states website which breaks down the definition of each code found in the columns themselves.

Pick their brain and see if you can ad value to their business. make yourself valuable to them and they will teach you. 

I'm sure your experience as a contractor will be valuable to yourself and others in the REI world and in the BP forums.
