Owning a property with the sister is about impossible as she is not good with money or business minded.

I would rather spend some front end money now and do a relocation, then be able to use simple side-by-side units than to be forced into stackables or all-in-ones.

Given your question however, I get the sense that this might be your first time managing a project like this and so would strongly advise that you connect with a General Contractor that you can trust as it will end up saving you a lot of time and money over doing it on your.

(Not actively purchasing as my money is tied up in the market right now)...so with the 2 lenders i've gotten here:STR DSCR Rural (not a log cabin or other non-conforming structure) just remote sfrHybrid loan 15% down, interest only investment loan with seller paid points to get to ~8% and reduce closing costs DSCR would use long term rental rates to establish monthly DSCR and then offset monthly with average DTI and 800+ credit and high cash reserves as long as DSCR is .75+additional appraisal to establish STR rate estimates to be used alongside the standard long term rental rates5 year prepayment penalty with reasonable terms

He is a mentor of mine as well, and is not so interested in making money but rather he told me that he likes to see 7% in his passively invested accounts, so I offered and he accepted that I would pay him 8% APY On the principal that I borrowed. 

They believe putting it on the MLS will make the most sense to them.Like everyone else, we are always willing to partner with people that want to learn through experience and find more propductive ways to find deals.There is money to be made in real estate in this current economy, if you find deals that have not yet hit the MLS.

They agreed, including them paying all closing costs, and we had set a price in the lower 400ks… I asked for more money, which they obliged to add about 10k to, but just today they said their partner pulled out.

With a lot of these deals, they will be very disheveled, and you will need to buy them with hard money instead of conventional financing.
