Highly unlikely to be considered spam.. that is if those 3 websites are not penalized by SE's. I recommend surrounding your anchor links with content. This is infact what many SEO pro's do! Also, homepage links are more often than not, the more powerful of links..

Make sure it doesnt look like a footer link - they can have diminished value

It depends on how they are hosted. If all the websites share the same IP address there is the potential to run into a problem. If you bought 20 websites and did this I would say it might catch up to you but even with three you run the risk of being slapped on the wrist.

Also depends on the nature of the link, anchor text and area on the website.

I'd say that having a few links here and there would cause no problems at all. However, be careful not to build up any spam type link building pages. Natural external links with different content should be fine.

Are all these websites publicly registered in your name (no privacy protection)? If so, I've read that Google can check the Whois site ownership records and determine if sites owned by the same person are linked. In such a case Google might devalue the links or even penalize the sites.

If you own a handful of sites and interlink them, as long as they are relevant to each other and provide the site visitors some benefit by pointing out other relevant resources then any SEO benefit they might provide one another is just an added benefit and would not likely trigger any type of penalty (regardless of whether they are on the same IP or not) in the event of a manual review by a Googler. Hell, you can interlink a handful of sites that you own that are unrelated and not worry about penalties. It's perfectly natural for site owners to link to their other sites.
Now this is NOT true if, say, you do this with 100, 500, 1000 sites. Doing so with that many sites would almost definitely result in penalty should a Googler manually review your sites as a result of a spam report.

I recall MC saying 12 or so interlinked sites are OK with different content . But there are so many gray areas in the variables to this , I'd approach it with an experimental caution.
