I have had a lender guide me in the conventional loan direction, which I could then rent out likely as a Midterm rental.

I put $50,000 down and now make $3,000/month from this property.Here's the breakdown:- 6 units in Indiana- $425K purchase price- $50K down- Off market & direct to owner purchaseI collected $2,885 in income the first month I bought it...Last month I collected $6,810 📈 And making ~$3,000/month in free cash flow.

Layer on the fact he has your card and you are not only paying for all of the materials but also most of the subs directly could be problematic.

Not aware of direct data for your question.Large apartment owners spend big money on this question and usually answer it by gauging demand via vacancy rates and Days On Market.

Well, I've been trying to share a local lender that can work with you but the forum rules won't all me to post his contact information. 

can i direct message you to exchange contact info?

If it was the same as the listing agent, then likley sites like Zillow.Another route you can go is look at the competition on Zillow and see how many contacts and applications have come through.

If you need some recommendations on contacts let me know, I have a few that my investors work with pretty regularly. 

So I contacted a contractor and he said the whole house needs to be demoed because there's a lot of mold, yet he said he didn't look at the additions, just the mobile home part, and was only there for 3 minuets.

I would personally advise to shop the home really hard the next few days and get a few buyers interested before contacting the title company, just in case the contract with the seller expires and you could lose your deposit.
