A good contractor that has established themselves in Detroit and a realtor/broker that runs all over Detroit checking out properties I find on and off markets.

Wondering if establishing heirship would/could potentially work...

Disclaimer aside, my short answer is create a land trust, transfer into it, adjust/replace insurance, redirect all accounts, and establish a bank account for the Trust. 

Even then, many won't lend unless you have a long-time and established banking relationship with them. 

Faster approval, more flexible terms, and less stringent qualification criteria.Tip: Establish a solid relationship with private lenders and clearly outline your investment plan to gain their trust and secure favorable terms.

It is true that more experienced investors will often have better construction networks, resources, and established processes that will allow them to pay more and somehow profit more.

But especially in ODC's case as they have so much going on and have grown so quickly that who's in charge of what exactly isn't always clear and systems/quality control not always well established.

If you have $100,000 in your brokerage account to borrow against, why not just use the money and secure a traditional loan, versus gambling with an unknown and variable future rate?

You will have a difficult time selling the park with the house attached down the road even after you fill it up and improve the CAP.And a second word of caution since I am sitting here spewing advice... those two vacant TOH homes depending on condition and the 6 vacant spaces should have zero value in establishing the park's value. 

Or keep them and fix them up but, you are right it may be gamble because, everything may be fine after it is fixed, or it may be other expenses that come up.
