P&I alone on a $700k house is close to $2900, people should be lining up to rent it at that price.  

Ideally you want to get to the point with your buy and hold operation where you have enough surplus cash flow coming in each month where you can cover a line of credit for your properties.

I am thinking along the lines of under 6k.  

I’d call your local bank and just do an unsecured line of credit or a personal loan for such a small amount and pay it back ASAP

I have the S-corp established with a bank acct & a credit line that I would use to help with any expenses if necessary but I don't know if I can pay for anything thru the business if it not owned by the business.

I anticipate this area to (for better or worse) gentrify substantially during the next decade.This is not to mention the new Rush Line BRT that will be built in the next couple of years (https://www.maplewoodmn.gov/1168/Rush-Line-BRT).

A shared fence is owned by both parties if that fence sits on the property line.

The roots are already lifting up the pavement and causing potential hazard, it is just a matter of time until it finds it way to the sewer line.

We were going to do traditional financing, but the HOA reported that 92% of units are rentals, thus making it a non-warrantable condo, hence our predicament.We have a couple financing options lined up. 

I am willing to pay the extra to have the pluming main line scoped looking for tree roots ect.
