You will need to verify two years of employment. If you were unemployed for a period of time before your current employer, it is still okay. You will need to provide your previous employers information along with your current employer, when completing the application.
Yes and No. If you want a conventional loan to purchase a home or investment property you will need 2 years employment in the same profession. If you want a private money loan aka hard money loan this wont be a problem. With private money loans you will need a larger down payment. The minimum down payment I have seen is 25% of the purchase price. An option is you could put 10% down and have the seller carry back 15% or 20%. This answer is based on what I have seen work here in California. I hope this helps.
