The first few years are zero cash flow, but then 5-8% CoC from years 3 to 7 or so.

I inherited my father's home and am entertaining someone who has cash offer for the house.

I never regretted keeping my first house as a rental because it cash flowed very well from the beginning and as years passed and rent increased it became an outstanding decision .However, our home was significantly less expensive than yours.

I have invested in several syndications in the past 12 months that are kicking off a 5% cash on cash return on my investment. 

.: I would love others to look up their market stats but I am not seeing mobile homes as depreciating assets in regards to their resale value.We bought a mobile home Dec 31st 2017 for $55,000 because the guy needed cash before Jan 1st.

They pay me good monthly cash flow and are paying off my mortgages, and I do them a solid once in a while and let them improve my homes the way they want.

If it is light, a dscr purchase would be a great option as it is typically 30 year fixed and around 7% give or take depending on cash flow, credit, and leverage. 

From cash flow point, not sure if it would make much sense to invest 180k to have an income of may be 900$/ month (that is if we dont use loan).

You can refinance next year when rates drop, which could lower your mortgage payments and give you some extra cash.

I'd get a small HELOC in combination with cash and/or partner with someone else to get a deal done.
