Two buy and hold opportunities

[Andrew Call]

Hello, This is my first post here on biggerpockets. I live on Maui, Hawaii, and am loooking to start REI, I have been studying and looking up deals for a while now.

2 opportunities have presented themselves.

In short, one mansion style home taken apart in sections with every piece retained, due to being built in wrong place too close to ocean, ready to be rebuilt. 150k to buy, haul it to any property, permitted to rebuild. offer of 120-200k to have demo team rebuild it as desired, materials alone worth 1.5M+, can sell at 2-3M or rent at 15k/mo. FCFS person with 150k.

Second opportunity is a home for 599k, 500 down to close, owner is second lienholder looking to close out Bank NY first lienholder for 455k cashout. Wants to do a double escrow. Willing to negotiate on some terms. house in great condition, highly rentable, in medium area, for 1800-2500.

Any suggestions do these numbers work for 1st time buyer, and where to find investors?

thank you.
