You would probably need to issue a W-2 for your wife.On $100K, it likely will not provide a huge benefit to add your wife, as you would likely not max out contributions in your own name, but having her as a documented employee of the company would allow her to rollover existing savings from another retirement plan into the account.

3) the house is in a 'non-disclosure' state (my term for: not required to disclose RE sales);  so doing 'comps' online seems questionable 4) IF the house actually sells for anything near $125k - $150k??

you don't owe a mortgage, so there is no time clock ticking away for paying this back (plus interest). you also mentioned you have a full time job that sounds like it pays well. why not take a break, save the money you need, or pay as you go per project using your paycheck. if you haven't had to borrow money at all for this project, why start now?

They're great to work with, operate nationwide, cover vacant and occupied properties, charge you month-to-month so you can cancel if you sell the property, also can cover ACV instead of rebuild value, which saves you a lot of money. 

I really wanted to get an investment started before I continue on in my medical career so I saved up money and just purchased my first investment rental property.
