@Asher F Jacobson You would need an engineer to evaluate the structure and stability, and the possibility of beach access (you would also need to make sure that environmentally and legally, you could create beach access).  

You should be able to find contractors in your area that works on mobile homes regularly and can help you evaluate cost scope of work etc.You can check with mobile home park managers and mobile home dealers and movers for recommendations

I've attached a copy of a CMA with several properties I would like the appraiser to take into consideration when evaluating my property.”The appraiser responded with the following statement:“Reconsideration of value.The borrower states that using comps that sold in the subjects market area forces a lower appraised value or what we appraisers call an appraisal.Location is still the most important factor in all appraisals.

Keep in mind in metropolitan area such as Dallas, there are a number of big players in this arena that have the ability to evaluate and pay cash for any deals that may be out there

Have you evaluated your local market? 

@Wei Wu I highly encourage you to educate yourself on what is it you're trying to do prior to jumping in.Some of the questions to consider evaluating:1) is your partner putting any money into the project?

@Marian SmithCurrently I was set up on this order, I think I need to re-evaluate:1.

Looking for advice on how to evaluate MHP listings.

https://www.thetaxadviser.com/issues/2012/dec/clinic-story-06.htmlIn determining whether the income should be classified as ordinary income or capital gain, the court evaluated nine criteria: (1) the taxpayer’s purpose in acquiring the property; (2) the purpose for which the property was subsequently held; (3) the taxpayer’s everyday business and the relationship of the income from the property to the taxpayer’s total income; (4) the frequency, continuity, and substantiality of sales of property; (5) the extent of developing and improving the property to increase sales revenue; (6) the extent to which the taxpayer used advertising, promotion, or other activities to increase sales; (7) the use of a business office for the sale of property; (8) the character and degree of supervision or control the taxpayer exercised over any representative selling the property; and (9) the time and effort the taxpayer habitually devoted to sales of property.

Probably, but for the area, I think the argument could be made either way.Someone once told me that a good judge for evaluating whether or not a house would work well as a STR is to see if it would cover costs as a LTR.
