Ensure the DSCR calculations work with the high LTV and your credit score, especially if the lender won't use MTR or STR income.Lender Criteria: Some lenders won't work with new operators, some only use market rent, and others will use STR estimates or income statements from property managers with similar properties.I hop the bullet points make it easier to understand.

Especially if the CPA/firm is working on a (high) flat fixed rate.

Getting a mortgage without a job will be near impossible without going with an alternative loan product that will come with a high down payment and high interest, which is not the "househacking" way. 

I'm not personally associated but know the folks and highly recommend them.

Let’s say your high bid was $100,000 and you refuse to close.

The real estate market is strong with property value remaining high. 

I'm looking into multifamily (duplex & self landlording) in my local area to get started, but my tri-state area (CT/NY/NJ) has a high entry price point that I'm concerned with over leveraging myself and losing liquidity on my first deal. 

One last advice I can give you is that MORE is not better, choose low maintenance high demand locations and the rest will fall into place.

You need to do this stuff because it's too easy for tenants or potential buyers to neglect the water bill, and the Detroit Water and Sewer is high.

I'd also highly advise against ever renting to anyone that has the intention of doing STR arbitrage.
