For the long-term investor seeking fixed income from rents, I would state in the agreement a percentage of cashflows.What are reasonable percentages for either of these scenarios? 

You can also seek out seller financing or check with local banks and credit unions that may have some more flexibility on the DTI ratios.Hope that helps and good luck!

MLS is soliciting offers for purchase, while wholesaling is about contracts seeking the party of the second part (the end-buyer).No real estate board will allow a fully transparent Contract to be posted.

I am seeking to establish relationships with like minded individuals with mutual aspirations to grow and develop their business. 

Once you have decided for sure what your niche is going to be, you might seek advice from an attorney and/or a CPA (or tax accountant) to help you decide to protect you personally.  

This is my first time seeking hard money funding and I have requested 100% financing.  

Seeking contractors in my local area!

IMO, there's nothing special about B&H, it's just a classical offer to purchase.However, there are differences between Residential (small 2-4 units) vs Commercial agents (5+) and if you're going MFU, be sure to seek a Commercial Agent - - their approach and understanding of investing is WAY different and will be an asset to you.

Seek something that you are passionate about and are happy to work at.

Message me if interested and more in detail on what you're seeking and budget.
