I would get very close to breakeven, but you are still living for practically free (not counting repairs, maintenance, and management) while paying down the mortgage on a monthly basis.I have never purchased a new property to house hack, but I would run the numbers like any other investment property.

Section 8 should really take care of all repairs and should terms tenants lease ASAP. guaranteed 1 year rent. unless it has changed. 

How do you find GCs to handle your property repairs and turns?

My question is - Does anyone have any thoughts or wisdom about how to sue the previous seller to get them to pay for foundation repairs?

I would review the property's current and potential NOI (after you complete repairs/renovations).

If the latter, give her notice, if the former-hopefully your lease has a clause about allowing people in to repair things (with notice) and that they (tenant and repair person) need to be respectful.

It will help keep you organized, streamline your communications about the repair both to the tenant and to whatever trade person you use to do the work and make your bookkeeping related to the repair easy.

,he foreclosed my home after 60 days and there’s reasons such as a storm ripped the roof off and I had to use $ to repair.

When used as an Operating Company, the traditional LLC can enter into contracts, handle repairs/contractors, enter into property management agreements, collect rents, and advertise.

Just won't be able to make enough with the repairs needed to make it worthwhile.
