I currently just bought my second property (a quadplex- 465k- that I am living in the basement so I was able to get owner occupant financing- doing one unit as a MTR and the other 3 long term.

Always leave on good terms. 

I’m looking to invest in multi unit properties for long-term buy and hold and would need help financing.

Go into detail about what happened with the tree picture. 

Please email me for the details. 

Assume 8% mortgage rate and 30-year term.

Look for a small/mid size local bank that specializes in this, they will detail what you need, survey, building permit, architectural plans and a builder contracted for starters.Or when you're ready to subdivide/redevelop you just sell to a builder and have them split the lots and transfer title to you for your smaller lot, he keeps the others and let him mess with the utilities and building. 

My guess would be that as this GP is doing 1031 as a TIC into the deal he would be a little less likely to want a sale, which is a taxable capital event, and would like to keep his money invested and sheltered from taxation as long as possible which tends to fit with my investing style of long term/preferably forever investing.        

You did a great job on most of the details but it looks like the floor plan you started with is now the issue and is not really correctable.Looking at the Zillow map of the area, I see very few houses over $400K and most around you are about $100K+ under yours. 

There was a lot of information I didn't mention in this post since each company and individual can operate differently so if there was something I failed to mention, please feel free to leave a comment).The terms Hard Money Lender and Private Money Lender can be confusing because people sometimes use them to mean the same thing.
