Major systems like HVAC and septic must be in working order.If any of those items cause an appraisal to fail, you can consider an FHA 203K (construction) loan. 

I highly recommend using Quickbooks Online, especially if you are planning to use a remote bookkeeper or CPA.   

In addition to the above, once you put your apartment online for rent...you will know if it's reasonable or not based on the number of inquiries you receive.I just placed my 1/1 w/ Office online and received 60+ inquiries within 2 weeks.

Next would be online crowd source, then HMLsNo need for LLCSame. 

These national online portals work good on properties that attract the Good crowd. 

I've only seen the KREIA ones online. 

but yes, it definitly takes a major hit on ARV just like if it was on the freeway, train tracks etc...

I imagine appraisers take a similar position on geothermal, but if anybody knows for sure, I'd love to hear.I do understand that the vast majority of buyers don't yet understand the value of tools like these or the cost/benefit of factoring decisions like this into a purchase. 

Either to a contractor(investor)that does major rehabs or to a home owner if it is close to move in ready.  

If you are avoiding "D" areas, you have to expect the vast majority of properties will negatively cash flow.
