And you are taking a risk of opening those walls and finding out the studs are at an irregular spacing or 18" apart, which is common where I invest. 

And I say that as someone that does think the ability to add density with ADUs is a great start, just like they commonly did in the late 1800s and early 1900s in every city that experienced major growth.Overall the solution to housing affordability is 15 years out.

Hard money lenders (MICs in Canada) are by far the most common type of OPM finance.

It is common for courts to award tenants triple damages and attorneys fees for technical defaults by landlords in areas like security deposit disputes or other common mistakes.

Then there's typically expenses like lawn maintenance, snowplowing, common area electric costs, the water bill and garbage pick up. 

They no longer allow this on investment properties because fraud was too common.

Common projects are large multifamily apartment complexes focused on a value-add strategy to reduce risk, taking Class B products and improving them to Class B+ or A equivalent.

In multifamily value-add investments, common risks include:Not being able to achieve target rentsMore tenants moving out than expectedRenovations running behind scheduleRenovation costs exceeding initial estimates (which can be a big deal when you’re renovating hundreds of units)When evaluating deals as potential investments, look for sponsors who have capital preservation of the forefront of the plan and who have a number of risk mitigation strategies in place.

Utilities - is that just for common area heat?
