What type of lending should I be looking for?

[Brock Y.]

I am a novice when it comes to different types of lending ( Conventional, Private, etc.) so I am looking for some help as to which route I should take.

Credit: Not so great. 650-700. 

DTI: Great. If I had 750+ credit I could get a conventional loan on a 750k+ house.

Assets: Have a few properties but do not want to use them, 401k yada yada yada

I am looking to purchase MULTIPLE SFRs (40-60k) over the course of the next year and was hoping there was a lender or a type of loan that would allow for this with my prequals. I am not in the market to keep getting hard pull on my credit just to be denied due to Credit Score.
