Amortization can be great as it allows deductions and can be added back towards income qualification.Depreciation, amortization, depletion (like Bill mentioned, forests, oil, gold mine, etc only has so much useful life/value) can be added back and a few other items as well (home office deduction, depreciation on business mileage on sch C line 44A can be added back at 23 cents per mile, and etc.Fannie Mae did 1 year self employment tax returns back in late 2012 maybe but I have not gotten a 1 year tax return decision on FNMA lately.However Freddie Mac (4 financed properties max) you can get 1 year self employed tax returns all day long even with down payments as low as 5% down (OO).

I don't mind if a tenant works from home as long as that work does not create any strain whatsoever to maintenance of the property, or cause inconvenience, noise, and liability to anyone else.For example, buying and selling stuff, requiring UPS or FedEx multiple times a day for pick up, drop off, sometimes many packages on doorsteps; running a misery, conducting a yoga class, hair and nail, pet grooming, are all going to have frequent visitors that may park in neighbor's parking spaces, and you might be liable if a dog being groomed in unit C bit a baby being dropped off for baby sitting in unit B.  

Thank you  @Elizabeth C.

Thanks @Elizabeth C.: I will be honest, I do not know to much about Handford California.

C) Call all the Zillow rental ads in your target markets.Tell them that you are an investor looking for rental properties in the area to buy.

@Elizabeth C.

@Elizabeth C., it is actually in the tenant's lease that "all repairs, whether to be done OR not are at the discretion of the landlord".
