They typically work their local market and have more detailed estimates. 

:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+, zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680, some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Essentially when I assign my agreement to the end buyer that buyer would do due diligence to inspect the property.

When you are talking about best ROE (return on your equity), DSCR Loans are generally going to be a best bet ***as long as you don't qualify for conventional options*** - typically DSCR Loans will have better leverage than more traditional Multifamily financing, but when starting out and starting to scale - the leverage options for the Agency-backed conventional Multi-unit loans are going to be your highest leverage option by far - however, people typically max out on these options pretty early on - until truly working with large multifamily (like 200+ unit properties) that qualify under Freddie

Then the judgment would need to attach to the property and then you can foreclose.Issues that could come up are I assume there is no third party servicer to claim the payments were or were not made- so there is a he said she said - if they also occupy the property and statements were not sent you cannot charge interest typically on the loan.You will need an attorney involved to see what if it is still collectible.

Properties with significant equity and have a mortgage on it the mortgage company typically pays it so they do not get wiped out.

Because cash out refis are not the same as typical refis, they already have a higher rate attached to them and if the lender knows it’s an investment property then good luck getting it to the cash flow.There is only so much that individuals can afford to pay for rent.

But typically these are already home owners so it may be a better than average tenant base as far thrashing the property. 

Make sure you know the value the ADU will add to the property before building the ADU. 2) The financing on an ADU is typically far worse than for initial investment property acquisition or is often not leveraged (HELOC, cash out refi, etc).

The idea for these folks is that if you are banking on appreciation, you are essentially speculating rather than investing.
