Lucy,It does look like you are referring to the minimum interest, or prepayment penalty, of your existing lender as well as the 'seasoning' period of any potential new lender.Most HMLs won't have a prepayment penalty on a rehab-bridge loan, but a lot of long term refinance lenders would require a period of time after you purchase it before they would take the new 'after repair value' (or, seasoning).

The new investment earns $24,000 a year, but the cost of the mortgage + the equity loan will be $22,332—and that’s before you account for taxes, insurance, maintenance, capital expenditures, vacancies, etc.

Use the dscr loan or the bank statement loan mentioned above.

It would be a different type of loan than the one you bought the house with in your own name. 

If I was to somehow turn my rental into a business, would I start qualifing for business loans etc. through the Sole Proprietorship or LLC?

I did a DSCR loan the other month at 8% and $2,300 in lender fees.

I'm finally looking to get out of analysis paralysis and pull the trigger on my REI journey and i want to start out as a co-host on AirBNB to learn the ropes from someone more experienced, learn enough to where I feel comfortable to host my own and earn a few dollars in the process.The only issue I have is that I have no experience as a co-host and per AirBNB's standard, i currently do not qualify as a Co-Host.

I read in Brandon Turner's Managing Rental Properties that most banks do not loan on properties owned by LLCs. 

The high speed train is actually finally getting built.

My clients in Texas and Florida have been receiving interest rates below 6.5% on FHA loans, so it’s there to be had.
