Real estate appreciates over periods of time so it's a snowball effect.

This project highlighted our ability to significantly enhance property value through strategic renovations and effective project management, resulting in a successful and profitable sale.

So you can't "foreclose".However, I'm 100% certain that what you meant to ask is effectively, "Do I have recourse and can I get my house back if the buyer defaults." 

Pre-understanding of the area/market, willingness to fix and live in an outdated and damaged home.

But the damage caused by hanging them (namely puddying the holes and touch up paint, or repainting walls if touching up doesn't work) will come out of their deposit. 

What else should be doing in terms of tech, CRM, networking, social media and marketing to have max effects on mentee locating, market identification, tenant marketing And deal finding....

Yes, you can ask them to be out by 10/29, but if they don't leave what will it cost you in terms of eviction costs, lost rent, damages, etc.2.

If they just needed one more month, they might extend and pay the premium.I mention that, because if you are OK with the resident and just want them to sign a lease, tell them the MtM price will go up effective September 1, and is $400 more per month. 

It could be an easy fix like this or a bigger problem depending on the factors at play (are the joists accessible, will it mess anything else up if you just jack it up and reinforce, is there water damage or structural damage to the foundation causing the sag instead of just old joists, anything else going on like a supporting wall or posts under the floor, wiring or plumbing runs involved etc.).

That means that the debt is covered by the income (after the add backs). so there is no effect on your debt to income when going to buy a primary.
