However, if I take my resources and spread it around, I can weather bad times better.

For example, using 70-80% leverage could preserve your cash for more deals while maintaining strong returns.A blended approach might work: pay cash for smaller deals to avoid delays and borrow on more significant properties to spread risk.

If you buy multiple properties, you can spread out your risk and avoid putting too much pressure on a single investment.

That spread is hard to come by as many wholesalers grossly overestimate the ARV and undershoot the rehab.

Biggest challenge is they spread themselves too thin and have no processes, so are unorganized.3) NEVER install mechanicals in vacant Class C & D buildings! 

15 year fixed mortgages are very underrated a 200bps spread is enticing as well as lower transaction costs.  

I could be way off, but I really don't think you can buy homes at the tax sale in most circumstances with $100-$200,000 spreads between purchase and sales price. 

Trying to figure out what I can/should expect to charge for 1)Purchase price; 2) Down payment and; 3) the spread per month if any on what I pay per month.

Selling the rentals via installment sales could also spread out tax liability.This post does not create a CPA-Client relationship.

I hopped on the roof with the garden hose to defend the property (even though initially it was contained) when suddenly an ember spread to a palm tree (that had been neglected to be trimmed for years) that instantaneously atomized/vaporized into hundreds of embers and spotted fires on several homes.
