If the agent is not working out for whatever reason, cut the tie and move on. 

Every deal has a challenge—whether it’s a seller with an unclear title, a property with zoning issues, or just finding the right buyer who actually sees the value.I’ve been navigating all of this while working on land and mobile home deals, and honestly, the problem-solving side of it is what keeps me hooked.

Quote from @Raymond Kalonji: In your opinion, what would be a reasonable minimum credit score?

You could also get a line of credit for about $150k (you should be able to borrow 75% of the value.)The reason I suggest this is…1) you save $40-$60k in selling costs. 2) you have a lower blended interest rate (2/3rds at 3.25% and 1/3rd at 7 or 8% instead of the whole $500k at 7 or 8%) saving you another $1k/mo in interest. 3) you only pay interest on that $150k when you actually use it, not from day 1  Unless you hate this property, or want to buy something you can’t afford without selling, that would be my plan.

Conceptually you want to take an approach that minimizes your need to be on site - and for that reason I would advise against BRRRR.

If the credit screening costs $25, then you earn nothing.I believe there are exceptions for a higher fee, but you have to stick to the actual cost of the screening.I would talk to an attorney before charging more than $25 per applicant.

If so what were the circumstances and what was the reasoning?

With 30% vacancy in the area, filling space could be a challenge.NNN leases are great for minimizing expenses, but how much control do you actually have?

That is if purchasing EXISTING performing investment real estate AND have very good clarity of every facet of the transaction ESPECIALLY reasoning for seller selling, AND you have decent market intelligence. 

There are several reasons why it makes sense to market to sellers instead of buyers.
