For your taxable accounts you have a wide variety of solid choices that are trending well now and look solid for the future based on demographics.  

@Sarah I would suggest doing some demographic research.

Has lots of interesting information about demographics, economics, urban planning and growing areas.

Most are undesirable, some fare, none good in my opinion.Is it possible after reno work to target a better quality tenant demographic or is it in a D grade area.Why is the place paid off, you should be leveraged since this property would likely cash flow with 100% financing.

I'm not sure if triplex in this spot would work well.I suggest a different demographic to proceed with your plan.

If they have a decent amount of properties under management, they'll be able to give you a very accurate rent estimate.Trulia is awesome for demographics:  You can see crime, school ratings, percentage of home ownership, a lot of great information.

I will keep probing to hopefully find that one prospect that fits into our property  plans....So you really have to understand the demographics of what the typical renter in that neighborhood will be like.

Just remember Mobile/Manufactured homes just like traditional RE is a very local biz and every geographical area has its own demographic and economic dynamics.

You gotta know the area, the economy, the politics, the demographics, and even the weather! 

I have other clients with STRs in Phoenix that are still doing quite well now, mostly because they cater to a different demographic.
