If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

It will usually give the conditions for the return of EM.

High quality property management if you don't want/can't to do it yourself3.

After experiencing different types of inspections with all kinds of properties from custom builds to existing, it all depends on your end goal , I highly suggest you reach out to a team, really strong team such as @Jorge Vazquez.

if you can build at 50% of after value I'd hire you and I build the cheapest of anyone I know in our market and minimum rates. there's 3 builders that build at our rate. only place I can get us to 50% equity is in miami florida and that is new construction that is selling at $1000 per square foot and up and high density 300+ unit underwriting with incredible economies of scale. columbus has lower construction costs but lower exit. we focus on urban core. my best suggestion is look at urban not suburban for higher valuations. you can't control what new construction appraises at so do it in less risky areas. 

I'm tired of wasting so much time on dead leads.. does anyone have a good way to get decent leads of high motivated sellers?

@Joseph Chiofalo is a good local lending resource and dually licensed RE broker, good for some high level market insight.

Would you make an offer on this property based on these projected returns?

If you have cash, know that 99% of wholesalers will have low repair values and high ARVs that don't match the actual data or upkeep of the house.Also, ask if this is being daisy-chained, meaning are there other wholesalers or investors in the line between the person offering you the deal and the seller.

Having that cash flow upfront means you can reinvest it/leverage it for better returns.
