What types of discounts for SFH bought in bulk?

[Tyler H.]

I found multiple properties for sale that seller is willing to offer short term financing.... I have several SFH rentals (S8) and have been looking for ways to expand, but have been stumped on the financing aspect. I was searching for seller financed deals when I came across these. Here are the basic stats... Looking for creative ways to structure deal so that I can obtain these properties with the least amount out of pocket.

Investor has up to 12 SFH local to my neighborhood. I am told he will negotiate a bulk package. Houses are 3 and 4 bedrooms, all currently leased sec8. (Im very knowledgeable about S8 so this topic is not about it). They are all listed for about 150K-200K, but arent selling because they have tenants and cant be shown to "retail" buyers.

I am a realtor, so I have a bit of an edge for negotiating a good price... Will make some money back off of sale, and will be able to sell if necessary.

Any deal structures? Obtain portfolio loan and have seller carry back portion? Acquire under market, and use new appraisals to lower my out of pocket? BTW I dont need all, even 4 or 5 would suffice.

Thanks in advance
