I called a successful investor I met at local meetups who helped me walk the property (first time for me) and estimate a rehab budget so I can run the numbers and figure out what I can offer in the current market.

We are currently spending $20-30K per month on marketing.

I also know people who are currently doing this.

I am 28 years old and currently live in Findlay, Ohio.

Simply put, it will not last for over a month.Therefore, IF I want this property, I cannot wait for my current rental to sell, get the funds in the 1031 Exchange’s escrow, and THEN pursue this house, as it will certainly be gone. 

I do get the rent in checks and transfers currently to my personal bank.

I am leaning to rent by room, given I could use the extra cash flow, and I currently work for a property management company so I have a good system in mind to use. 

As far as replacing your current interest rates of 3.5-4.5%, that is a bullet you would have to bite to pursue access to equity.

We fully own the property, but an equity loan minimum is currently more than we qualify for, can't find a personal loan, all due to credit scores.

You can start by picking random Zillow sales or currently listed properties - then, use the rent estimator and rental property calculators/tools to determine what the returns would be on that particular deal.All the best!
