After 1 year owning this property, we now have one year of data!

The truth is buried in too much data for complete accuracy. 

- Should I pay taxes, Insurance, and HOA fees myself to ensure they are paid?

This matters because if I’m getting financing, or to ensure the association is solvent.

High, Low, or Just right.I then try to find as much actual Expense data as I can.  

They have access to raw data on your neighborhood and can show you the standard DOM (days on market) and the list to sale price (how much are homes listed for versus what price do they actually sell for?). 

@Jermaine Riggs   Remember the 6PsPrior Planning Prevents P*ssPoor Performance There are steps that you can be taking today that will better ensure you will be able to qualify for the best of terms on your purchase in TX.1. have a Mortgage Broker run a Tri-Merged MORTGAGE credit report and pay the extra $15 for them to also run the "What If" score increase simulator to know how best to pay down debt in the interim2. start eating MREs and saving like a maniac until you close as the more money you can show in reserves Post-Closing, the better the programs you can qualify for.etc,etc,etc,   

So management is more important than market.Of course, this doesn't mean that numbers don't matter, they absolutely do, and any turnkey company worth your time should have solid data-backed stats that you can use to run your ROI calcs.

As most things, key is buying right and ensuring that you have the right relationships to do so. 

Ensure that you have about 30% of the investment price available for investing.
