I find that investors can still cash flow if they are willing to adjust their models.

I visit and analyze the property, and estimate rehab costs (with experienced inspectors and contractors), add a buffer for unexpected repairs, and provide a financial model with an ROI comparison of a traditional rental vs. short-term rental.Any guidance/tips (positive comments only please) would be greatly appreciated!

My business model will not change (much). 

That is the business model for C/D investing.

What if you inform tenants that your insurance co requires all persons residing there to list make and model of  their cars.

I have done a bit of research on modular homes and think it might be cheaper than to build a place from scratch, however I am having trouble finding a model that matches my vision for this center.Does anyone have any experience building in this area of the country or have any advice regarding modular homes vs building (construction loan)?

And yes that $1200 a year will be a large help to the business model. 

What a reassurance that I am on the right track here and that you have had significant success with the exact model I am looking to implement.

We take a similar approach with some of our buildings and model our numbers with land-value at disposition.

Our buy and hold model is to buy homes in Columbus Ohio with private capital, stabilize the asset, and then refinance to put more permanent financing in place.
