You mention you have no experience in these types of parks and your first deal you want to take down 100.When I was working for a GC we did a condo project for a developer who never developed a building before and he sold his company (it company) and used the entire amount to develop real estate.He ended going bankrupt because his inexperience with his experience and his designers and every mistake they made was multiplied by 150 since that is how many units there were.

That severely limited the number of lenders I could go to, so I ended up finding a loan product (that costs a premium, albeit) thru Velocity Capital Mortgage that allows fully-amortizing or IO payments (for first 10 years) which will help me build cash flow and accrue title seasoning while I find the right time to pull the trigger on a fully-amortizing DSCR product Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

The first is equity. 

I also have no issue getting conventional financing, but am going DSCR in order to get up to the 75% LTV.I don't think i really need any more quotes at this time, that is not why i am posting this, just wanted to get other's thoughts.....

My partner has a stable full-time job, but his photography business is not as steady as he'd like.We're interested in purchasing a multifamily property in either Baltimore, MD, or Hagerstown, MD, to kickstart our real estate journey.

and most of the time is  bad management, bought the wrong price, Interest and Insurance to the roof and, I cant get out the Bridge loan to do a DSCR loan etc ...Simple hands on, work do research and minimize risk. 

I've seen some posts arguing about design and color scheme choices that are in and out of style in rehabs and flips so I figured I would give my first hand advice.

Also, if I was to take out $50k from the first property to put a 25% down payment on the second house, would there be an easy way to tap into the rest of the equity in the first house if I wanted to take another $50k to buy another house in the future? 

They turn up all the time.

Is it a bad idea to rent out my childhood home for the time being?
