Anyone who has a claim can come back up to two years after the sale and redeem the property.  

So I am wondering whether it is legal to claim both home office benefit and free from FICA on Rental income from IRS, or otherwise you have to select one of them.

We are ready to start on making our goal of 12 years ago come true, to build our custom home mortgage free.

However, I have never heard anyone state a case in which Legal Zoom has failed any customer in regards to setting up an LLC as a real estate investor.

Having done that I am now preparing my first mailing for motivated sellers.I wouldn't discourage you from door knocking, I think it can be a valuable learning experience, however I would have to agree with @Lynette Braun that "touching" the customer with mailings or social media prior to meeting with them is more in line with your long term success in this business.  

They said owner didn't live there and they saw some people with kids who claimed as tenants, but they haven't seen these people for a couple of weeks.

I switched to them after a couple claims from one tenant about the rent check getting lost in the mail (one time it probably legitimately was).  

(Dealing with maintenance, doing move-ins/move-out inspections etc) My work hours are 8:30 am - 5 pm (although I typically work until 8:30 pm or 9 pm daily) I noticed that prospective tenants always ask to view properties in the evenings as they claim they can't request time off from work.

You should list every charge to their ledger, even if you do not intend to collect, for the following reasons:Seeing a full list of charges will discourage the tenant from taking you to court, particularly if you have photographs or video to back up your claim.If the tenant does take you to court, you can defend yourself AND make a counter-claim for the full amount charged.

Can my partner/girlfriend claim the income and expenses?
