I don't even know what CAD is......When the county recorder has a good, up to date online index, then I can use that combined with my ability to get actual docs from my title accounts.  

A fairly common practice in MF is to refinance the entire mortgage after the value has appreciated due to some combination of NOI improvement and cap rate compression.  

What defines 'PIG" is functional obsolescence, age, CapEx overhead due to the previous 2 items, class of tenant attracted to location and structure, etc.$30,000 in SFR space buys 1 type of thing

The owner of the house was also fighting to evict the tenants and his lawyer combined the two cases. 

Vacancy -Banks like to see 8% but a range from 8-10% is good.Garbage - Some communities bill this separate or combine it with water.Cost that people forget are snow & ice maintenance, village license and inspection costs, accounting, and annual preventative maintenance.   

When I started buying MH's in resident owned park communities or on private land and reselling them I obtained my RE brokers license once again because of the volume I was doing.I've been a developer by default as when I do purchase a lot/parcel and replace an old home with a new one or purchase an empty lot/s and develop them out I either sell them or keep them in my rental inventory.I've been dealing in distressed MH & site/stick built properties for 20 years and do a combination of all the above so I think it prudent to keep all my licenses and qualifications current and in good standing.Lastly, I've been a construction defect, park management/owner harassment, drainage and fraud expert witness, Industry expert for the California State License Board, consumer advocate at large for various TV, Radio and printed media outlets as well as a forenencis expert and consultant for myriad state attorney's general, district attorneys offices, county, state and federal agencies for over 20 years.

This is the function of an agent.

About a week later, call whatever number USA.com shows or use online tax/property records combined with the almighty Google to find a number for the homeowner if you can.Two (possible) touches in a week puts it in a motivated seller's mind that you're serious.

We also do annual inspections before we renew leases, and we let out tenants know that this is to make sure everything in the house is safe and functioning like it should.
