What you need is data on what rates/costs/terms you can get on DSCR and then base your decision on real figures.  

Happy to discuss all of these strategies over the phone just shoot me a dm.

Given the above current owner is in the red every month $350 and is asking $475,000 for the park.If I am mistaken on any of these assumptions please let me know as my comments are based on these assumptions.From what I am seeing the seller is way out of whack with their asking price. 

I'm not sure how old your "oldest son" is that can hear them arguing, but if he's older and is ok with recording them on his phone (if he can hear it, he should likely record it), then you'd have some sort of proof of threatening behavior and lease violation in case you call the police. 

If you did, you have to renegotiate with the homeowner they never contacted me back ( I texted all ) Work those phones!

I don't "freak out" over opinions but I do base them on verifiable facts, not a story I heard or a guy told me.

Based on what Nathan Gesners relative is selling their 23 acres for  1 mil an acre we have about 100 to 120 million dollar prop once brought in. we have been approached by the big boys we got an offer last year of 20 mil and turned it down LOL  .. my partners are all younger than me and bought their options in their Roth IRAs  its a pretty cool long term play with some risk of course.. but oh such upside for them..

You earn appreciation based on the market value of the property, not your equity.

Here's a snippet from our starter course on becoming a Local Real Estate Developer and it will help you understand where the value comes into a development project to see how to weight the equity and deal terms based on the experience of the partners in the deal. 

@Bryan Nwokem since I don't know nothing about real estate since I'm also new the fact that you said this is a new build and based on the rent I would just go $1,700 a month that would be me if I was in that position but then again I don't know numbers.
