Most of the crews aren't family units who seem pretty used to living arrangements that aren't as "posh".It's looking like if we start branching out into management, we'll start at 15% and go from there. 

There's a chance they will say no (because they showed you 6 properties and expect to be paid) in which case perhaps you can arrange for their managing broker to set you up with a different agent in the same brokerage and give the first agent a referral fee for their efforts/ for referring you.  

I know I likely leave something on the table doing this but I’ve had people not move out on the expected date and then been in a pickle for what to do about the new occupants who have made their arrangements to be in a certain date.

Should the tenant arrange for it and pay for it?

Hello everyone, I've done 3 buy and hold rental properties, and now I want to do flips, I need investors and I have some that have shown interest, in addition to speaking to private lenders that are willing to fund 70% of the LTV (based on the desired property)I'm seeing a lot of deals from wholesalers, but the problem is, some of them close in 2 weeks and some as long as a month, and they don't take conditional offers, and the good ones fly off the shelf really quick.My question is, how does someone like me close one of those deals within this short period, how do you arrange the equity and financing with little to no inspections sometimes even.I'd like to know how do I prepare myself to be able to close one of these good deals right away when they are offered to me and many others?

As long as the arrangement is legitimate, you'll still be able to deduct eligible expenses like property taxes and maintenance costs.In terms of accessibility modifications, such as adding ramps, these could likely be deductible as capital improvements on a rental property.

Are there any verbal agreements or arrangements between the current Landlord and Tenant?

You arrange the LLC deal so that in the waterfall, you and Sis get the majority of profits over this baseline threshhold.

What you are describing is a fully thought out partnership or pre-arranged circumstance.
