I've done fairly big renovations where in most cases, Im replacing almost everything in/on the house.

Always use a property manager to keep your real estate investments as passive as possible and keep you compliant with Fair Housing laws.This way you can learn to manage the property manager and learn from experience as you go.If you buy a bunch of properties all at once, they may not all fit your buying criteria, there may be deferred maintenance that needs to be dealt with all at the same time, and you will not have accumulated the management experience building your portfolio one at a time.To Your Success!

All sec8 rentals are subject to review and approval by the housing authority issuing the vouched.  

We had no experience building a house from scratch but I did have a bank willing to lend to us.

A three bedroom house for 800/mo is crazy low!

What is she doing now in terms of paying for housing? 

I bought 14 houses basically for free by harvesting the equity in my houses by doing 5 cash out refis.

Also when you are under contract and get condo docs, make sure to read the meeting minutes (for the past year if available) they will indicate if there are any talks of an upcoming special assessment (which you don't want).

I only have 1 property under my belt and am currently house hacking my SFH. 

If she went to buy a house and applied for a mortgage, I think the lender would say the same thing aka you don't qualify until you get this removed from the credit report.
