I used to ask if they have ever been evicted, but they seem to think if they move on their own, five minutes before the bailiff arrives, that it's not an eviction.

There are many determining factors you need to calculate in order to arrive at the asking price's true cap rate and what cap rate it is currently worth.

It is the proper calculation of the expenses to arrive at a true NOI that is often done incorrectly.

Being new to all of this I am having trouble determining what percentages to use for  Maintenance & Repair/CapEx to arrive at a monthly cash flow figure?

Complete intermediate paperwork as it arrives...5.

From NOI you would subtract capital expenditures / reserves and debt service to arrive at NCF. 

In order to arrive at that total, you would need to contribute $3200 extra per month towards the principle. 

If you purchase the tax lien from person C's daughter, there must be a procedure for petitioning for a tax deed and taking ownership of the property. 

No one pays rent until you promise no more rent increases and no more evictions (unless the tenants approve; they become the bosses in your property).If the Jim Brooks Act, a home-rule petition, is approved by the State Legislature and made law in Boston,then other cities and towns across the state, especially Cambridge and Somerville, will be able to adopt it.Here's how the Jim Brooks Act would create RENT STRIKESwithout ever mentioning "rent strikes."

So the "process" to arriving at a valuation might be similar but defining a "good deal" isn't anything that a one-size-fits-all-course can bring to the table.
