@Bing Lin, The way in which you and your wife are reflected on deed probably isn't that big a concern with the 1031. 

. $500k won't buy you much in San Fran but is a pretty healthy budget in Jax.One smaller factor is that Duval county doesn't charge impact fees on new construction (and is the only county in Florida that does not) which is great for developers but not so great when there's no money for maintaining our schools.https://www.jacksonville.com/news/20190423/duval-voters-to-decide-on-proposed-sales-tax-referendum-to-pay-for-replacing-repairing-renovating-schoolsAlso this isn't Florida or Jacksonville specific, but in times when the stock market is particularly volatile real estate investing becomes more appealing even with lower returns.Personally as an investor I find all this out-of-town investing a bit annoying (increased competition and increased prices) and am concerned that these properties potentially aren't well maintained.

That’s what’s concerning about getting into out of state investing now.

Issues of concern are getting an ITIN, annual tax compliance including Form 1040NR, partnership withholding forms 8804/8805 if applicable, and FIRPTA if applicable.

A lenders main concern is your ability to repay the loan, if you lived your own they deemed you not able to.

I bet they aren't too concerned with who they place in your units. more turnover=more $$ in their pocket.

I have concerns that this might be asking too much but again this property has amenities that others I've checked out seem to lack.

My biggest concern is heat in the winter time.

Our concern would be that the hours we account for will be paid via payroll and that is subjected to payroll tax and then we pay taxes again when we file. 

My concern on the 30 days is more that I want to make sure I have time to find the proper tenants for it.
