A manufactured home can work, but it all depends on the building codes of that city/jurisdiction. 

The risk is getting the work done well enough and to code so when the buyers building inspector walks it, there isn't a list of 50 things to still do. 

Make sure the downstairs is actually a legal unit.If the bottom level is being advertised as a unit, confirm it meets code (eg., egress, permits, proper electrical/ plumbing).

Depreciation and other deductions aside, irr on our sfr have lagged the s&p all without collections, code compliance as well as escalating municipal rental regulations of permits and licenses.

At minimum you’ll need an architect (to design plans that meet code), a general contractor (to build), and potentially a civil engineer (if there’s grading, utilities, or drainage work). 

I would highly recommend working with a CPA that is familiar with both US and Canadian tax code to determine what makes most sense there.• Are STRs still worthwhile after factoring in PM fees, insurance, repairs, and higher financing costs for foreign investors?

We explained to the code officer that the dates were blocked out for personal use.

From a legal perspective, my understanding is anything less than building code (wall mounted) leaves me liable for injury.

Here’s the Part Most Investors MissThe biggest risk in development isn’t construction…it’s time.A 12–14 month build exposes you to:rent fluctuationslabor issuescost creeptimeline slipinterest rate changesThis is why a lot of small developers in FL are shifting to modular or prefabricated builds — same codes, same quality, but far shorter timelines.Shorter timeline = lower risk = more certainty about rent performance.It removes the “What will rents be in a year?”

I usually just plug in a zip code into smartrentalinvestor.com and it analyzes all the properties in that area for me, shows me the best performers by cash flow and cap rate.
