I used it to purchase an off market deal and am about to refinance to pay it off and pull out equity (550K total). 

and then a commercial lender the rest of the loan to purchase?

I started my real estate investing journey this year with the private purchase of a off market house that went awesome.I then found a interesting triplex/warehouse property, went and looked at it with the listing realtor, crunched the numbers and decided that it made financial sense.

Investing in Stowaway SS appealed to me due to its stable demand, lower management costs, diverse tenant base, scalability, resilience during economic cycles, and potential for generating passive income.

High purchase prices, need to choose right areas within a market.

Above all, if you decide to remain in Boston for the next several months but decide on Atlanta as an investment market, you should ideally visit the respective markets several times before making a purchase.

How did you decide on a fair purchase price looking forward a year of two?

Depending on the area you purchase in.

My partner didn't have good credit at the time of purchase so her income isn't a factor for the HELOC because she isn't on the mortgage or the deed.
