This is what insurance is for. can you think of a reason why someone could file a lawsuit where your insurance would not cover you?

You must work at least 750 hours per year in a qualified RE business.So most people who have high-earning W-2 jobs outside of real estate won't qualify.But the unique thing about RE pro status is that even if you don’t qualify but your spouse does, you can both file jointly and claim the losses from your RE investments to offset your other active income together.It's an incredibly powerful benefit if you do meet the criteria.

Since the Internal Revenue Service (IRS) doesn’t consider child support taxable income, I would not consider it in the rent calculation unless you have a HUD-specific home.According to hud.gov, “[rental property] owners must count alimony or child support amounts awarded by the court unless the applicant certifies that payments are not being made and that he or she has taken all reasonable legal actions to collect amounts due, including filing with the appropriate courts or agencies responsible for enforcing payment.”So, does child support count as income for renting?

There "may" be a policy form out there that doesn't require this, but all the ones I've ever seen follow these standard insurance principals.

I am concerned that he/she is either filing bogus small expenditures OR performing services himself/herself and making profit.

During this time, you'll only be paying the interest, which means your payments won’t reduce the loan principal.
