They should be able to give you an idea how much life each component has left and what the cost will be to fix it.  

I agree with @Curt Smith, checkbook control is almost essential depending on your type of investing and a Solo 401k sure beats an IRA if you are eligible.Contributions limits are roughly 10x higher, there is no custodial requirement for the 401k, you can take participant loans, you don't need the additional expense and administration of an LLC to have checkbook control, there is a built in-Roth component, a spouse can participate, there are additional tax benefits, there is generally greater privacy, and the plans are often quicker to setup and cost less money over time especially compared to most IRA LLCs.

At least in the market where I live, condition is an integral component of a valuation.

Lue C.If you have self-employment activity, you may want to consider a Solo 401k instead of an IRA.Contributions limits are roughly 10x higher, there is no custodial requirement for the 401k, you can take participant loans, you don't need the additional expense and administration of an LLC to have checkbook control, there is a built in-Roth component, a spouse can participate, there are additional tax benefits (UDFI exemption), there is generally greater privacy, and the plans are often quicker to setup and cost less money over time especially compared to most IRA LLCs.

I think renters tend to look at each component of the cost.My added advice point would be to find a comp that you want to emulate. 

They also offer a renovation loan component.  

I have investing in small business that sometimes involve a real estate component, but I have never done a straight real estate deal.  

If you average out the cost of replacements and the service life on the components you come up with something like this.  

One is that when you walk into a house you need to know what the major components to look for are.

I'm looking for someone who could offer all 4 components I need to buy on a large scale:1.
