What are my options to cover the $100k difference to still get this house with 0 down?

Noah, I would call the local officials and ask them for your options.

But there are many other options that governments can take to incentivize productive behavior.

To me sounds like something an amateur would do who is trying to save a few dollars hiring the cheapest vendor option out there.

I'm not sure any reputable fencing company would want to put in a fence where neighbors are disputing a boundary line.The other option, of course, is to just get the survey done.

otherwise i agree with the others - 50K just isn't enough...Hi Nicholas I’m starting to rethink my strategy and what would be the best option to get my foot in the door.

.- HELOAN option - There is a small chance that you can pull out the equity using a DSCR HELOAN but make sure to calculate the blended rate and total payment before moving forward and comparing that to a full new 30-year fixed loan.

Find your syndication partners and discuss these options with them. 

When offering a seller options you are selling speed vs convenience, do they want to move on fast?

At least explain the situation and they'll give you an unbiased, informed answer to let you know what your options are.
