Do you think those rent-to-value numbers are really a reflection of invest-ability?

I would make sure that the lease and any guaranty accurately reflects the deal you agree to.

You can find other lenders that will lend for more heavy value add properties but your terms will reflect.

That being said if you want to make a career out of real estate choose a major that reflects your passion.In every student market you will have access to MULTIPLE property management companies, agents who manage portfolios and leasing offices at apartment complexes.

Credit score requirements should also be reflective of the type of rental you have.

If the later, you need to make sure your Insurance policy reflects that (Ordinance & Law coverage is the most common name for that).  

All of the data is shown right in front of you, and you have to apply your own heuristics for selecting the appropriate comps including their age, distance from the subject, counts of rooms, size within of each other, lot sizes, etc.We can discuss all day long about how good or bad Zillow data is, and honestly, it depends very much on the market, and how quickly a sale gets reflected in the public record.In my SoCal market, it's actually pretty quickly, and I often end up using a blend of suggested comps from Zillow and my own comps that I import from other places such as Redfin, your free MLS alternative.

Your net passisve loss carryover, if you have one, will reflect the repair expense.

Add new taxes in the mix that just came online this year and next year prices will reflect the tax hikes.

So your numbers should always should reflect current rents at this price.
