To give some context, what I'm needing done is as follows: roof repair, 3-5 floor joists replaced or "sistered", surface mold remediation, 3 bathrooms remodeled, hardwoods sanded/buffed/finished, exterior and interior paint, drywall repair, granite countertops and new appliances in kitchen, new HVAC and ductwork, branches cut away from roof, gable vent repair, insulation.  

Termite damage can be much worse than it appears on the surface... or not.   

Rates of return are at market, anybody offering you 7 in today's market and I see red flags. on the surface, I think it may be a good strategy for someone who has a few hundred K in the bank, that needs insurance and wants tax deferred growth.  

They buff out the old surfaces and spray on the new coating.
