@Tim Ryan I should have said the unit is uninhabitable and by rehabbing it will produce rental income, so a years rental income/ capital invested = CoC return?

The rehab estimate seems very low and the ARV seems really high in my opinion, just based on a tiny bit of research looking at what this property was listed for recently (it hasn’t sold), and what the surrounding similar properties are worth (~$250k).

It wasn't a good deal $90k because of the age, weird layout, and the bathroom was tiny. 

It's shedding material from impact of sun's rays, that's how elec is produced.

It takes about 10 years of never missing a payment, using light leverage relative to your income, and using a tiny fraction of your available credit card limits.

But if hold on them for awhile and pay them off, then your family and kids and enjoy the income they produce.

**I had a tiny home I wanted to use ADU laws to make legal.

As I see it in the current market, STR is now a way to get a really good, appreciating asset to pay for itself, not a way to produce a meaningful amount of cash flow after all expenses. 

Craigslist wasn't pretty, but it was easy to use, and it worked (I found lots of great tenants via Craigslist) ...unfortunately, over the years, Craigslist produced fewer and fewer tenants, and more and more spam.  :( These days, nearly all my new tenants come from Facebook Marketplace.  

I do not have my numbers as well organized as @Greg Scott but my estimate is upper 20% annual return on average.The 3 i am currently invested in, one seems likely to produce an outstanding return (High risk, high reward), one is conservative and is performing to projections, and one i have significant concerns about but has not had a capital call.
