Permits are basically only pulled for electrical and plumbing of if they get caught.. its the only way to make the rental houses cash flow in many of those markets.On top of that licened contractors many times simply wont work on those type of properties there is no money in it for them..

I have some of the required funds in a HYSA, but will most likely need to draw from another account and I'm curious which method is the most efficient in terms of taxes/capital gains, penalties, loan repayments, etc.Based on my previous transactions in the market, I estimate ~$45k cash to close: $20k for the down payment, $15k for closing costs and prepaids, and $10k of starting reserves.

What's the highest success percentage method to find a previous tenant's new address for this? 

I want this to be acceptable long term if I keep this method of financing. 

@Treza Edwards "I am reading the Rental Property Investing book and implementing the method that focuses on cash flow and that strategy states you need to have $300 cash flow per month, per property.

What other methods should I use to acquire another property? 

BRRRR method is also a great way to go - good luck!
