This was an Oct 15th acquisition and took about 2 months to clean out and repair/rehab. 

I have his phone number but wanted to come up with a good proposal before I call him and pitch my idea.

A roof on the 600K property will cost more than on the 300K property, but you have more roofs to repair on the multiple 300K properties.

It usually starts with a thorough walkthrough of the property to list all repairs and improvements.  

I've acted as a "deal warning person" to many new California and a few NYC investors who I've talked to in person, Zoom, and phone calls who want to buy the Midwest or South because the price points are lower.  

Remember, turnover is one of your most expensive costs, so try to eliminate downtime and repair costs by doing it right the first time.What are your tricks when it comes to renovating or maintaining rental property bathrooms?

Hi Randall-Congratulations on buying a rental property well back in 2020.I am sorry to hear the property is now cashflow negative $200 a month.Your question is should you sell or continue to keep it with the negative cashflow.Depends on your personal goals and if being negative $200 a month plus any unexpected repairs or vacancies is affordable to you, but if you can solve the negative cashflow by turning the property into a furnished mid-term rental, for example, your future self may thank you.To Your Success!

Even in the nice locations, most top out around $2,800.Of course there is also your increased insurance, vacancy, repairs, CapEx, and the never mentioned reduced rent on the main house since having a stranger living in your backyard usually isn't appealing to most renters. 

I'm thinking that repairing the plumbing leaks and getting the soil dried out could be a permanent solution.   

Deduct NEW property taxes after you buyDeduct home insurance costsDeduct maintenance percentage, typically 10%Deduct vacancy+tenant nonperformance percentage(we recommend 5% for Class A, 10% Class B, 20% Class C, good luck with Class D)Deduct whatever dollar/percentage of cashflow you wantNow, what you have left over is the amount for debt service.Enter it into a mortgage calculator, with current interest rate for an investment property, to determine your maximum mortgage amount.Divide the mortgage amount by either 75% or 80%, depending on the required down payment percentage - this is your tentative price to offer.If the property needs repairs, you'll want to deduct 110%-120% of the estimated repairs from this amount.Be sure to also research the ARV and make sure it's 10-20% higher than your tentative purchase price.As long as the ARV checks out, this is the purchase price to offer.It is probably significantly below the asking price.
