When I comp a rental, I use the biggerpockets rent estimator then I follow it up with a call to a local property manager to verify that's an accurate market rental rate. nothing will beat calling a property manager, they have all the information you will ever need or want to make your final decision about a property.

I'd also recommend researching "asset-based" lenders which evaluate a decision to provide financing based solely on the house and deal itself (not your personal income or financials).

I was so intimidated by the large price tag I was going to have to put into my property to get it rent ready again, I decided to not make a decision and just keep kicking the can down the road. 

They aren't relevant estimates, they should not be taken into consideration in decision making. 

I have moved from one property to 4 and I am having a hard time with investment decisions.  

Moving into a condo unit, in my opinion, will be moving you in the opposite direction of what you're ultimately looking to accomplish.Best of luck to you on your decision!

The lender will make their lending decision based upon the Debt Service Ratio of the property.

But I wouldn't want to underestimate the power of a big news-generating company like Tesla announcing the CA->TX move as it feeds into the headlines and momentum of Austin as the new up-and-coming tech center in the minds of many news-watchers out there and will make decisions over the years to come of where they want to be/move to be part of the action of the future. 

Those are the three ways that I know that you can approach the decision.

The time restraints may push you to a decision that you regret later.
