If you are living there you can keep the 4% rate.If you are not living there you can rent it out to pay for the property taxes. 

Is it worth paying their annual subscription fees and do their 30-day rent guarantee mean anything if they aren't refunding the payment?

If I terminate lease with PM_1 for this duplex end up paying commission of one year on one side tenanted unit and 250$ for other side vacant unit.3. 

Determine what price you can pay for the property.

You pay a bit more, but you get exactly what you want and don't have to worry about maintenance for a while which is obviously a savings.I live in the Woodlands, so considering the location of my home and rental property, I'd ideally like to build this in the area of The Woodlands, Conroe, Spring, Tomball, Klein, or Cypress. 

My guess would be its a "you get what you pay for" situation.Can anyone shed some light with recent experiences?

Do you think SCI can possibly pay a mortgage for ?

There is no set time for the county to foreclose on the property via a tax sale, according to this article purchasers of the tax lien certificate have to wait 5 years, as the owner has a redemption period after the tax sale, so you could be waiting a while, and if I'm not mistaken, you have to pay the taxes each year until the 5 year period is over, then you have to file for a deed or file a lawsuit to quiet title.https://smartasset.com/mortgage/how-to-buy-tax-liens-in-cali...Hope this helps,Dustin
