GreatSchools has a pretty sloppy methodology that doesn't necessarily do a good job of identifying Great Schools;2.  

Some older parks are laid out so tight with short lots you can't buy a home to fit the lots today and new zoning requires set backs further shortening the replacement home.Some parks are simply dead or near dead because they are full of ancient 10'x40' or 50' homes and the lots are so small you can't buy a replacement home for those tiny homes.

So based on the methodology, you've got "normal" rents on cheap houses so high "income."  

Is there a different methodology or price point when calculating ROI or resale value.  

This methodology results in days like today where Freddie notes "falling rates" because Mon-Wed of this week were generally better than Mon-Wed last week.

But there *are* strategies and methodologies that will take some time to discover. 

I will absolutely follow up on checking out the words, wisdom, methodology, and strategies used by both @Ellis San Jose and Rick H..To @Brian Gibbons you have made it abundantly clear to me that you are no slouch yourself in the's matters.This post that I quoted you in fills my nethers with all sorts of warm and fuzzy feelings.

You should check out the post on here titled "The Dirty Truth about the Guru Programs"  to put it all in full context, though.I'd suggest going through the podcast archive and finding someone whose lead generation methodology sounds like something you can and will execute on a daily basis and then start creating your own system for executing that methodology.

I'm two hours in and there is definitely a ton of good methodologies to be taken from it.

I'll give you some examples:Older furnace/water heater (not ancient, but certainly end-of-life).Vinyl tiles (lower-grade) or even better, rolled linoleum.Bedrooms without molding.Worn carpet.Roof structurally sound, but shingles at end-of-lifeThese kinds of things are easy/cheap to fix from an investor perspective, but they drive down the retail price of the property when someone is trying to sell it.
