I think you will find everything you need on one platform and happy to get you a free tour of the website

I like the West Mobile area, its class A area, you can definitely find deals there, 3 bedroom with 2 bathroom for around 220k or so, you may have to wait a couple of years for positive cash flow but properties there increasing in values better than others.

Is there a platform where I can advertise a pool of mortgages for investors to buy/invest in?

As experienced professionals, which of these platforms do you prefer, and why?

I was at a live tax deed auction once and the last property up for bid was a dilapidated 70s era mobile home on a leased space in MH park. 

It is already off putting that I could not be allowed even to use a tent or trailer, RV, mobile or tiny house even temporarily.

@Ashley Wolfe if the mobile is attached to its own land, you can use the 1 to 4.

Strategic Purchase: Acquired a discounted double lot below market value with a $17k impact fee credit.Custom Design: Built a 6-bed, 5-bath home tailored for co-living or multi-gen use, maximizing tenant appeal.Efficient Management: Managed construction, and self-managed operations to minimize costs.Premium Marketing: Furnished the property and used multiple platforms to attract quality tenants quickly, achieving full occupancy.What was the outcome?

I only mention this because I noticed your mention of Furnished Finder, which is the only platform I list my MTR, and FF caters to 30+ day stays. 

The trust one can build up over the years on platforms like BP, Youtube and others is insane.
