Flipping is also a full time job...or a second full time job. 

I recently did a refinance personally, and bullet pointed out all the ways in which the listing agent did a horrible job of marketing the property, caved on price during negotiations, etc, among other things, to make the appraiser more comfy with an opinion of value significantly higher than I purchased the property for.

However, the Tax Cuts and Jobs Act eliminated this restriction starting in 2018.

Bigger worry is job market and interest rates.

Like I said, it's our side hustle (we both have full time professional jobs and a houseful of kids), but we do the management ourselves. 

Even small improvements never go as planned, bigger jobs will have delays and unforeseen problems. doing this with tenants in place could prove to be disastrous.

@Jon Lee I actually just left my Regular 9-5 job early to go to a Lunch/Meeting at 11:30am.

Do you know any good contractors who are reliable and do a good job?

Dave with Pro Interiors does a good job. 

The doors are grade level with only a 10' clear height.It is currently 30% vacant but I've been told this is because they are using a big firm to lease and manage the space, who apparently aren't doing a good job on these kinds of properties.
