However, when you pull up the current market, you see that nothing comparable has sold in the past 6 months, and that the currently listed properties have been on market for far too long, meaning this is an area where there are no buyers, no appetite for these homes.

I have already contacted two other contractors for quotes in order to obtain three total quotes.I understand that some investors like to also make use of lower-cost options, such as neighborhood kids, but as I am running a business, I would like to maintain a process that is repeatable and predictable and that may also adapt to long-term needs, such as landscaping and weed maintenance.

Long term, option 2 produces significantly more wealth over time.

One side is rented long term while I live in the other.

@Ruben Banuelos assumables are not all they're cracked up to be, they can take 4-6 months and the lender doesn't get paid on it hence why it takes so long. 

If below 1.5, will likely to keep renting out with main house and ADU separately, around 7 k/mo.If I sell it, will likely just pay the long term capital gain tax.Quote from @Wilson Lau: Competition is definitely high on the buy side, and I see more and more buyers coming in as we approach the summer season.

I am a new real estate investor looking to buy my first multi-family home as a long-term rental. 

Why do you think purchase contracts are so long and have such small print?

The numbers continue to make sense on this it’s just now a matter of how long do I allow the litigation to draw out (still acquiring those attorney fees) before just moving on.
