So I take what you have and what you expect, estimate the time it would take in a whole year of work and create my flat rate.I notice short term rentals are about 1 hour a month of work per property, since we need to track each property's Profit & Loss for Tax time, this is also tracking a mortgage and depreciation as well for that property.

@Lauren SanfordI barely learned I could resell and estimated around 50k at 0%.

Stock market returns estimated to be much lower next 10 years.

Just get lots of estimates, as they can differ by thousands.

No I have not been in person, and what you are describing is exactly what I'm worried about.I will say that I do have a contractor who I trust to do an honest thorough inspection (I requested several references who all gave positive feedback, and the one property I did ask him to inspect he found a major structural issue and immediately told me not to considering buying it).It seems like when most people run into trouble its because their estimates of vacancy, maintenance, capex were all too optimistic.

I’ll have to play with it.I haven’t gotten to the Estimating Rehabs book yet.

And then there's the huge cost to hospitals, estimated at almost $1 trillion.
