Units that are down and will take 4 weeks of rehab at $5k are worth less.Luckily there is a fairly easy way to evaluate all of these things, discounted cash flow over time using internal rate of return.Do a spreadsheet showing income in and costs out over time.

I only invest in either private pre-sales of pre-development properties at a substantial discount compared to their market value and launch price and rom a developer who I personally know, has a great track record and give me cheap developer financing by Mexican standards.

For many tenants adding a rental policy may actually drop their overall insurance cost if they already have car insurance, due to the bundling discounts.

Have covered many claims quickly and professionally, and with the discounts I get bundling I can’t imagine anyone being cheaper.

I applaud your tremendous effort and I do believe that eventually this situation will work out okay for you.

That is why many wholesalers don't last.The origination of a wholesaler was someone who purchased heavily discounted properties from Sellers and immediately flipped them as-is to an end buyer. 

Here in Columbus, Ohio, we are seeing tremendous growth and revitalization in the city.

At the end, you had to do the work no matter what.Now, regarding receipts, the Contractor gets a discount, because they buy in bulk.

Thinking you will improve the NOI and the CAP rate of a park by renting out the homes will lead you into a DEAD END with investors and lenders as we/they heavily discount or outright ignore that source of income when valuing the properties. 

Each market is different, in one of them a seller can put it on the MLS and get multiple offers in a week, so why would he ever wholesale it for a discount?
