I personally stage all our properties (rent a sofa/love seat for 100/month at the furniture rental stores, buy blow up mattresses, put them on moving boxes and put mattress sets and pillows so they look like real beds).

Then they stole/damaged the furniture.4) Stolen plumbing (fairly common).There were a few others, I forget them all, but you get the point.Having said that, I think there are people making big money in those same neighborhoods. 

FHA loans are for owner occupants only.Fannie Mae has some exclusions for that for folks providing housing for elderly parents, disabled children, etc, that are at 95% LTV.

Dina Harleth Not a bad idea, but it's just hard to match furniture around.

I am planning on teaching what I learn to my children, who will be helping me as needed.

Put furniture and items that have some value on the curb with a free sign. 

HUD approved those bedrooms based on no young children sleeping in there.  

Often the cost for a well ranked AirBnb/VRBO is not cheaper than a good hotel but the overall experience is much better and more comfortable especially when traveling with colleagues or multiple family members including children. 

I have a wife and two children.

I plan to keep all I purchase, and pass them along to my children, nieces, and nephew.
