It just meant problems down the road during the project.....something was always wrong,Cheap people tend to be unreasonably picky as well, and with no real understanding to back up their concerns.

You pretty much validated my concerns with purchasing or rehabbing within certain Class standards. 

Now, I understand that HELOC should be used for short term financing purpose and I am concerned that I may have made a misstep. 

What concerns me most is that statement: "I have yet to have a conversation with a seller"Here's the truth: It'll probably take talking to 50-100 prospective sellers before you even have a shot at getting a deal.You don't get to change that.You do get to decide how long you'll take to get those conversations completed.Reach just 1-2 sellers per week and it'll take you a year or two before you get a deal.Reach 10 sellers per weekday, and you'll likely get a deal within a month!

However, I am worried about the outdated electrical and water systems for safety concerns.

If you are younger and seeking to rapidly build a cash flowing portfolio, if you are wanting to continue 1031'ing into bigger assets, or if you do not have the cash to take down entire deals without financing, leverage makes a LOT of sense.If you are retired (or rapidly approaching retirement with a level of uncertainty or concern about what your post-retirement income will look like), it could make sense to begin paying off properties so that you reach a point where your expected monthly cash flow will exceed what you need to live comfortably after retiring.

If you do plan to refi at or around the 3 year mark when the PPP expires I would also ask your lender about a temporary rate buy down instead of / or in conjunction with a permanent buy down.

For us there is no perfect property to manage.I am more concerned with the owner. 

Is it just not my worry what their income is since the voucher covers the rent, or is my concern that if they only have about $950/month then they won’t properly be able to maintain their pets and their standard of living valid?

The seller has countered with the following conditions:- Loan to value (LTV): 80%- Earnest money held by seller's recommended property management company- Final inspection within 1 day of closing- Commission paid by to buyer's agent is 2% of final sales price.I'm seeking advice on how to proceed, as I have some concerns:- Why would the seller request an 80% LTV?
