I’ve considered mid and short term rentals, but from what I’ve seen, Baltimore city unfortunately does not allow new short term rentals unless the property is owner occupied. 

Build an SMB on top of your real estate (the reverse of #2)Short-term rentals and high owner-participation real estate businesses can have great returns.Obviously not for you if you just want passive RE.We are in the deep end here, where each case should be judged on its own facts and merits by your CPA.You should hire a professional to review your particular situation before you make an investment.

Personally I only use my HELOC on short term projects like flips, new builds and BRRRRs where I know I will be replacing the capital within months.You may be better off waiting a year and save up more cash or liquidate your index funds if the returns on a property will be better.

ThanksI bet that's a good short term rental market!

I am looking at short to mid term rentals 

Depends on really what you are looking for:-Speed - some HMLS can go "no appraisal" so can close very quickly and beat cash offers if you are in a competitive market to buy-Interest Rates - can range anywhere from around 8% to 13% (same with "points") but not usually as huge of a concern for flippers since the terms are so short-Leverage - depending on your risk appetite / capital - this is also a top concern for some (almost always over and above rates/fees) can see anywhere from around 80% LTC to even mid 90s LTC (including 100% of rehab budget)

but generally - new accounting and property tracking softwares fall short in one of two places: 1) they don't actually generate financial statements that a CPA or Lender will approve, or 2) They can, but the learning curve is so steep or convoluted it's impossible for you to get help if/when you need it (I imagine this is why this thread is a little slow right now)Have you asked your accountant what they think will work best?

Liquidity: If this is your first or second property, prioritizing liquidity (by cashing out now) might allow you to seize unexpected opportunities, especially if you’re actively prospecting deals.Since you don’t have a deal lined up yet, you might explore options to minimize the gap, like prequalifying potential deals or using short-term financing strategies to bridge the 4 months.Good luck growing your portfolio!

Quote from @Quan Dao: Hello Everyone, I am new to Short term Rentals.

SF has a limit of 90 days per years for AirBNB in the city otherwise I would keep it and short term it all year long.
