I'm based in Trumbull and actively looking to diversify into the MTR space as my next investment.

This is an area of many varying views. 

This will go easier with water-based than with oil-based poly.

Based on the policy, I understand that. 

I'd be happy to have a conversation about good investment strategies for this area based on what you're looking for.

Based on the information in your profile, it seems likely that this is your one rental property although you mention in your profile that you also let out rooms in your own home.Out of your four options I think the worst is No. 4.

Insurance is likely 100 a month based on other parks I own in the area. 

However, if you work with insurers based in Northern NJ you will have no trouble finding something that works. 2-4 unit properties are in abundance here and are often being house-hacked. 

Determining exactly how beneficial is based on a multitude of factors, but a cost segregation study cost/benefit analysis on your property is typically free and can help you decide whether the benefits offset the cost of the study.If a Cost Segregation Study had not been performed on this $560,000 single family home located in Phoenix, Arizona, it would have had first year depreciation of approximately $20,400.

I'm here because I don't understand and I'm coming in with assumptions based on my own taxes over the years and you've kind of put me down or made fun of me for being "surprised" at how the tax law works.
