pulling cash out of rent house

[Richard Carr]

Wanting to pull cash out of houses in TX that I have owned for a while and paid off.  I am looking into apartments.

excellent credit

Q What loan is the  biggest percentage I could get out of the house? - 80%, 75%?, etc

Q Should I use multiple banks (lending institutions)? - one for each house?

Q What are my choices for types of loans when I go and talk to the lending institution?

Q Should I do a cash out refi?

Need lots of advice.  I have been out for a while.  The last time I bought was in 2008/9 .

Thanks,

RCarr
