They both have solid roofs, electric to the pole and city water as well as natural gas.

@Marcus NarvaezI think you have a valid point about the agent.

Of course higher efficiency furnaces will cost you more money but save the tenant in gas bills.  

I work full time in the Land Department at a major upstream Oil & Gas Company in Houston.

One I am familiar with is Fairay. www.sbrefunds.com (Disclosure: I do not invest in it so you need to do your on research as the the validity of their return claims)

Ok, all valid points.

Gas, heating, appliances, snow removal, etc etc.They did say the BRRR strategy is being used with this quite a bit too because they get around 25% ARV equity.I must admit this is very enticing because I have such a busy life but seems a little too good to be true... which means it probably is.  

Fat number.I have seen people drive 10 miles to get 20 cents off a gallon of gas but get home to a huge For Sale sign on their yard for which they are paying 6% commission (or 20% of their equity to a Realtor).BP members are here to make money and if that means making a little effort to sell a property on their own ... just list it with a Flat Fee MLS listing company ... 

But there are always circumstances that could validate a shorter or longer holding period.And finally, if you're asking how long you have to hold cash (capital) after a sale before you can put it into the next deal it is irrelevant.  

They need to validate / confirm everything since at the end of the day, it their risk but as most people, after 2, 3, 5 times seeing that they get the same answer, they will trust you more and be able to act quickly which is in both your interests.Oren
