I thought about starting out with 1 single family residence for long term or midterm rental.

Hi, I am new investor and just got my first cash offer accepted for an investment property which I am planning to use for a long term rental.

On a short term hard money loan yes. 65% CLTV max 

By securing long-term tenants and maintaining the property’s condition, I’ve enjoyed consistent rental income and significant appreciation in property value.

Quote from @Matthew (Mateo) McDaniel: A hard money lender is typically used for short-term loans.

If I were to do so, I'd definitely look for small multi-family as opposed to SFRs, unless you're wanting to create a short-term rental(STR). 

The programs are quite easy 25% down on a dscr loan and 6 to 24-month terms and can close within 14-21 days send me your email or DM me and I send you the matrix for most of their programs.

Since it already cash flows, that could ease that burden for you.For funds, I'm not sure what your existing rate and terms are but you could always try a cash out refinance to fund the next property.

Short term bridge loan, they require much less down payment (10% or less) after stabilizing the units you can refinance with a better loan option.2.

Now it's stable, and time to take out the hard money with long term institutional debt.
