If they offer seller financing to us, what are their tax implications on being paid out over time?

First buyer had pre approval.

You paid $298, but your cost basis on paper is only $282. 

Even the best sales people will take 6 months to get begin getting paid due to the natural cycle of real estate, and many people don't close a sale for longer than that. 

I am ready to get my first rental property (already got pre-approval), and I also have 2 properties that I want to offer on (I did a fair amount of research on them).

If the loan is paid off in 6 months or under, the lender will get a big fine from Fannie Mae.

I've never paid a plumber to replace a water heater, don't know NJ prices.7.

I have an assignment Lease Option REI business and was wondering do other Lease Option assignment folks pre qualify their tenant buyers before you assign the lease option agreement and if so, exactly what process is used?

As far as the deposit, I had not yet paid it. 

I moved to Tampa, Florida but am still renting out my almost paid for house in New York and I'm loving the cash flow!
