I received two applications for the unit the I am showing.

I am a citizen of India and currently working in the USA on the H1B working visa for the past five years.

The property appraiser may request the applicant to provide additional ownership documents to establish title.1(b) Every person who qualifies to receive the exemption provided in paragraph (a) is entitled to an additional exemption of up to $25,000 on the assessed valuation greater than $50,000 for all levies other than school district levies.Exemption of homesteads.—196.031 

When a current apartment is rented with tenants, and you need to rent the place for when they leave, do you have them fill out an application first?

As with anyone, read the fine print and ask what fees they not only charge you, but what they charge tenants for application fees, etc... sometimes companies shift costs to tenants (to appear cheaper to owners) and it only hurts the process.

Yes, you take pictures, answer applicant emails, etc. 

This generally includes any 3,5,7,15 year assets placed in service 2018-2023.The de minimis safe harbor allows full expensing rather than capitalizing and depreciating small amounts paid for tangible property up to $2,500 (or $5,000 with an applicable financial statement) Hope this helps and good luck with school!

If lost, have him file out VTR-34 Application for Certified Copy of Title.

Underwriters serve the purpose of a scape goat if the loan application goes bad and your loan needs to be rejected.
