Credit pulls for the same type of loan within a short window (usually 14-45 days) are treated as one inquiry, so your score should be fine.

Short term my credit score did take a hit, but once the promotional transfers were paid off, my score jumped higher than it was before.These days, the "pure" zero percent transfers don't seem to be around anymore as they typically charge a 3-5% balance transfer fee as part of the promotion, but this is still better than current HELOC rates.

So you need to develop your checklists before you bring your first deal.  30 days is a very short time to execute and learn.etc etc.Use the above to start the development process for your wholesaling efforts.

It's a short term lease.

You can ask your CPA on the cost segregation short term rental loophole.If your partners credit is bad but you have cash, you can just cosign for the loan or go DSCR/hard money.Dayton is a solid market for BRRRR investing.

Rent would probably be a short term nightly basis. 

Lenders or investors who have short lock up periods but have years of experience feeding their business with new capital would give me more comfort but anyone who is just starting and is promising a rate of return or return of capital in a set period of time would be alarming because they very well could be reliant on fresh capital to make good on that promise and that usually ends poorly.

@Joshua MartinSince you might sell next year, a HELOC is probably the better short-term option—lower upfront costs and flexibility to pay it off when you sell.

I have multiple lenders that can do 100% financing for your short-term rehab loans and long-term DSCR cash-out loan options to refinance and hold the property once it has been rehabbed.
