Need Help from a lawyer

[Bintuan Zhu]

Two tenants from Ohio and I e-signed a lease for my property at Houston last year. They moved out 8/21/2016. We have argument on secuity deposit.

I have several questions. Could you please help me?

1)The tenant said because they signed lease in Ohio, and her father is an attorney in Ohio. They will sue me at Ohio. Can they do that? Or they have to file a lawsuit at Houston. We e-signed the lease. I live in Houston and property is in Houston.

2)They own me the late fee. Can I subtract it from secuity deposit?

3)If they refuse to pay late fee, Can I sue them for it? Their rent was late every month. The tenant said I can not charge them for it because I did not demand them to pay it before. I did mention (email) to them of late fee in last December.

Your help is highly appreciated.

Thanks
