There could be many, but usually the main issues that could break the deal would be Foundation, Plumbing, electrical issues where it could be costly to repair the property @Carlos Valencia @Albert Bui

Then literally hundreds of these of come across my desk seeking financing - and typically the pro forma looks great while the actual historical financials show almost no more profit than Simple long term rentals after paying management fees, higher interest rates necessary for these type properties, increased repairs and maintenance, and faster depreciation.There’s also a personal reason I don’t invest in these properties ( I DO finance them).  

Make sure to factor in 5-10% vacancy, taxes, insurance, mortgage, repairs & maintenance, lawn care, pest control, management fees, utility costs (goes in your name when vacant), turnover costs, and capex reserves. 

At the same time, housing operators are havingto repair damaged units while insurance costs spiral ever higher.Thebottom line: Revenues are falling while expenses are rising.Thereare no quick remedies.

I fall into the badly camp (so far until the property stabilizes after 2 to 3 years),  lots of repair issues.

Make sure the lease includes all maintenance and they need to be in charge of all interior repairs.  

This includes getting comps or an appraisal to verify value, lenders title insurance,  a proper note and mortgage,  and you must be listed as a mortgagee on the borrowers property insurance policy.Our lending criteria in our lending business caps our loans at 65% of the after repair value and we control all rehab funds as we hold them in escrow. 

You'll be able to learn the ropes of managing a property and coordinating repairs/renovations.  

No leverage, not much in the way of repairs as they are all rehabbed with long term tenants. 

Very few repairs and very little drama.
