Is that a bad idea and likely to annoy the sellers?

They also increased my line of credit by another $40k due to extra equity within the property that I can now use to acquire more units.

The humidity in the crawl space is not too bad, readings have been average to a little above average in the wood and air.I want to replace the flooring to LVP or LVT but need to have level floors in order to do this.

I am also extremely interested in Portfolio loans, but I have zero contacts dealing with those types of loans.Finally, I have an 'excellent' credit score, no debt at all besides 5 other rentals at 75/25 LTV (all cash flow positive) and a job that I claim over 100,000 in taxes, and have three years of consistent tax returns showing that.

The neighborhood matters, 20-30 miles (often much less) can make all the difference between good/bad vacancy rates and rent rates.

I heard David Greene talk about getting a line of credit with a bank and then make a deal that you refinance with them.

Local community banks and credit unions may have no seasoning period for their portfolio loan offerings.

Besides borrowing money from 401k, you can open a line of credit on you Primary house and lenders can typically lend up to 90% CLTV or 70 investment properties.

Every market has good and bad areas so be warey.When considering ROI on single family vs. multi, the multi will provide you with revenue to offset your house payment while you're living there. 

I utilized a HELOC along with 2 other lines of credit.
