Im reading a lot right now and this helps me a lot. 2 things I can't understand from properties I've looked until now ( which all requires a lot of work), 1- owners who wants to sell their property and tells me also the rehab price, which makes no sense for me,( even the rehab price for me, with a quick estimation is 30-40% less expensive then told to me. ), 2-  Realtors that don't knows the ARV or rent price after rehab.Thank you again best, Ilir

I believe the competitors are more expensive with unnecessary features.

Soon after, mold was found in one of the self-storage units, requiring expensive remediation.

The property will cash flow $500/mo or more after all expenses and cap ex reserves, as well as the payment on the SBLOC.

Besides putting together the best SOW using accurate/actual quotes as @Peter Mckernan and @Alan Asriants commented above, another key aspect is tracking expenses (bookkeeping) and monitoring the budget throughout the project. 

California is tough because it's expensive and tenant friendly but the right areas can make some killer appreciation.

Fairlawn is a bit more expensive and there's really low inventory in that area but Cuyahoga Falls is also a nicer suburb in Akron that does really good with rentals.  

Expensive markets are often desirable because many people want to live there, driving up demand and prices.Reno, NV, for instance, is a market that benefits from diversified employment sectors, including tech manufacturing, hospitality, and recreation.

Some of the most expensive and difficult properties in the country (and world) to develop were vaporized into potentially un-developable lots.

Cash flow (in my portfolio as a whole) covers my expenses.
