It's worth investing a few minutes or few hours finding out when so much is on the line. 

Are you looking to cash out on your existing properties to purchase the park?

I'm hesitant to give up my conventional loans on the next cash out refinance for DSCR loans.

I was able to rent the property by room and it cash flows about $200/month so far.

It cash flows without the utilities split but I am planning to hold onto for a long time so splitting the utilities seems to make sense.

You are not even scooping your initial investment so your cash on cash return is negative.

Here are some general guidelines: Lien Position1st Position LienEquityMinimum Down Payment of 20-25% (a 30% equity to sale price is preferred)Down Payment made in certified funds and not borrowedMaximum Funding of 70% ITV (Investment to Value)SeasoningMinimum of two monthly payments already made12 months or more preferredPayer CreditCredit Score of 650 or higherNo major derogatory trade lines (No 90-180+ days delinquent, foreclosure, repossession, bankruptcy, etc.)No decline in credit since purchase of businessTermsPrefer 60 months or lessMaximum of 72 monthsNo Balloon Payment preferredCash FlowBusiness has positive cash flow1.25 debt service coverage ratio preferred.DocumentationPersonal guarantee from a creditworthy individualStandard documents including Note, Security Agreement, and UCC-1 filing.Tax Returns on the business that substantiate profit and loss statements.OtherPayment history current and verifiablePayer Interview indicating buyer is satisfied with business and comfortable making paymentsMotivation for selling the note is not a result of a deteriorating businessConsideration of high risk businesses or geographic areasIn these situations, sometimes a partial is a better option. 

If you don't see real appreciation upside (both price and rent), it's just not worth the hassle.

Are there any house at that price point that would rent for $1200-1500/ month with 20k worth of updating?"

The investor has to be gaining cash flow or equity to make it worth it.
