Some of those people will go busted in the next year or two...I am looking for 4-plex too, and I have set a criteria that with 15% down, i need the property to be cash flow neutral from day 1....

The income alone from those properties would be enough to live on in 15 years and they'd be cash flow neutral for the first year or so.

Neutral or beige color for walls.

So, yes, I am not a very neutral adviser.

I agree with the others who say neutrals or opposites.

We use white trim and ceilings with neutral colored walls in all our rentals, even SEC 8.

I was thinking more neutral territory like Clearfield, State College, and Lock Haven; not enemy territory home to mostly Eagles and Flyers fans!  

IMO safest bet is probably to do that seeing as then they are the neutral third party responsible for tracking payments, holding the deed of trust, and providing the payoff statement when your client pays off the loan, etc., rather than having the seller do this.

Keep in mind that rental properties really don't add much to your debt ratio, or add much to your income, they tend to be close to debt neutral because of the rents offsetting the PITI. 

That being said, depending on odor there are other strategies to lock it in or neutralize it depending on the type of odor (acid/protein/uric/etc.).
