Worst case scenario is not being able to refi unless I come up with $50k.Austen Mueller, I tried using the duplexes and square footage to formulate the value of my 4 plex but was told that they do not translate and they would only compare another 4 plex.It seems like I may have to walk away from this deal. 

Your best bet would be to contact a local bank where the mobile home park is as they're more likely to lend compared to a nationwide bank not familiar with the area. 

Start with no less than a 4-plex because when you increase the rents for a 4-plex your profits are almost exponential compared to a single-family home.

A good rule of thumb is to compare the extra 5-10% down you are doing and the monthly payment with the higher interest rate.

I’m trying to compare other commercial properties that are similar and I am having a hard time doing that..I know commercial properties are compared differently than residential. 

What are the most important items to compare?

If you're talking about how to reimburse yourself with respect to your investor/partner, if I were that investor/partner, I would expect you to pass one the actual cost of that employee to the project.That said, I would also want to see multiple bids indicating that the cost of that employee was comparable to hiring a third party.

All the while the longterm renters provide good rents compared to the purchase price.

License cost a pittance compared to income potential.

Ensure that you're comparing apples to apples as well, meaning the properties you use for comparison's sake should not only be of a similar style, size, number of bedrooms and bathrooms but should also be in similar quality to the level you intend to remodel your rental.If you are working with an agent and are trying to buy on market, they should be able to help with this.
