The properties I am looking at will cash flow a teeny bit, enough to cover mortgage, interest, insurance, and 20-30% for repairs and vacancy.

The inability to turn over a unit if cleaner is not available on one dayThe insurance/liability aspect (all insurance companies asking if I will be doing STRs) When electronic deadbolts dying before guests show up etcReplacing damaged furniture during turnover (who do you compensate to handle that?)

In general know where your plumbing, electrical and gas line are and then place your majors first and work around.

You know, like the hundreds of thousands of people in the Carolinas who had no flood insurance and who have had their homes damaged or destroyed by hurricane Florence?

Between the annual reports and filing fees, and also the overhead necessary to maintain separation of assets so the corporate veil isn't pierced, the cost-benefit just might not be there.Might make the most financial sense (and most streamlined) to run her as a sole proprietor (Sch C) and carry appropriate and adequate insurance, which you should be doing anyway with an LLC. 

Most renters will not pay renter's insurance and that is a choice but how would they like not to have a choice about carrying insurance because of the potential liabilities and expense should you come up against someone like them ? 

I was quote a few insurance options for a $125k sfh rental and I don't know how much insurance  is needed.How much does landlord normally needed to be protected and protect your investment? 

The rest is personal responsibility, police, and insurance.

In terms of the funding options for your next deal:1) if you have IRA (Roth or Rollover) consider SDIRA.2) if you have your own business, consider solo401k. you might be able to move Rollover IRA funds into it. also, a better option than #1 above from a taxes perspective3) partner up with money partner4) look into leveraging your personal life insurance policy as a loan (if you don't have one, go get it)5) you can borrow against your 401k at work up to $50k. you pay interest and all back to yourself

The lender is required to sell the property for at least 95% of a current fha appraisal, if the property is upside down, in order to be reimbursed by fha, the insurer.
