Age is just a number.

Information on the tenant (I wouldn't want to touch a property with a tenant with a lease and lots of evictions, etc)  Age of big ticket items such as roof, appliances, HVAC, etc?

You are 23, you own rentals and you have built - that is HUGE for you age! 

Interesting that most people your age barely no what an Ira is and you are considering dumping it.

What age and condition are they?

@Michele B CagleThere is a lot of good info on BP regarding the age old argument whether insurance or an LLC is the best way to address the risk of owning rentals.

It’s probably because my credit age is so young.

However, because of my unemployment and age, I am unable to get a loan from a bank which is currently the biggest problem here.

there is no second level and its hard to tell by the roof and the age of house, if there was an expansion of part of the house at some point.  

After that you have to consider property taxes, income taxes, weather (both damage and mitigation), age of the house, HOA fees, construction (stucco vs wood, tile roof versus shingles), city utilities versus septic/well, location,location, and oh yeah,Location. :-) ($500k House in San Jose ca or on the farm in the Midwest.)
