Hit a snag in my investment goals :Scenario ;I have 85k Saved to invest I made 6 figures in 2018 Have 60k in equity in my existing rental property in Nassau county New York Good Credit BUT ....I lost my job last month and I’m concerned lenders will give me a hard time for not being employed, although I do have a small business that is brining me at least $3000 a month in profit.

As far as MF is concerned I wish it were so; but I have yet to see any uptick in availability of MF in any market close to my area.
